I have a 93 GMC K1500 5.7L TBI that I am swapping to Vortec heads. I got the Summit Racing 67cc heads, GM Performance tbi/vortec intake, vortec exhaust manifold and a RV CAM. I need to get some odds and ends together but I think I have 90% of what I need. Just waiting on parts, anyone done something similar? Pic related
>>29081782Pushrods, lifters, rockers all the same between both setups? Probably a good idea to verify.
>>29081841Pushrods are the same. I am not 100% sure on the rockers. I will go to the small local parts store tomorrow and ask the old man that works there to verify. I have new lifters. Cam is a K1102 Summit. Thanks anon, good points.
Here is the intake. I estimate 275hp and 380ft/lbs torque with 2.25" duals. Not sure what muffler yet but leaning towards a Super 44. Thoughts?
>>29081854"feet per pound" isn't a unit of torque retard
>>29081920take your autism meds.
>>29081938shut the fuck up retard faggot.
>>29081956have sex
Now that retards have pounded feet until their bicycle chain fell off anyone not autistic?
>>29081965let your mom know I'll pay double this time
>>29081854>I estimate 275hp and 380ft/lbs torque with 2.25" duals.Dude, just drop in a crate motor.What's the goal here?You're gonna nickel and dime yourself until you've spent at least half the crate motor cost, but only half the HP.Tell me to stfu if I'm offbase here.
>>29081998Not op but it's a hobby, right? Building your own is way more fun.
>>29082004>Building your own is way more fun.Fair point.
>>29081998>$7k for 47hp over stock
>>29081998>>29082052>>$7k for 47hp over stockThat's awful.OP, I wonder if you could find a LM7 5.3L / LQ4 6.0L at a junkyard.It would still require mods to install, but that's an easy +100 to +150 whp over a tired stock TBI 350.
>>29081920If you push 1lb with a 380 foot lever. Does that work out the same as pushing 380lbs (thats a big bitch!) on a 1 foot lever?
>>29082117The fact that multiplication is commutative doesn't have any relevance to the derivation of units. Torque is a cross product which means the units can't be interchanged. I know you were trying to be clever but you're out of your depth.
>>29081998I'm working with a good short block. I'm aiming for conservative real world numbers. At any rate the vortec head swap with the rv cam will give me enough power to tow my travel trailer. The limitation is the tbi system. I want to retain it for reliability reasons.
>>29082200Incel post.
>>29082312He must be fun at parties, though I doubt he gets invited out.
>>29082312>tried to be clever>got btfo>reverts to redditrylmfao
>>29082309Oh ok, that makes sense.Thanks and GL.
>>29082309For the tbi, you get the obd cable and tunerpro? Id do a better fuel pump too if you haven't and increase the fuel pressure spring. I like the tbi, it's fine for this imo
>>29082200I say lb/ft because im in fabrication but in going to start typing out ft/lb on /o/ just to get this guys forehead vein pounding.
>>29081854>275hpHoly shit just buy a DOHC 4 cylinder and put a turbo on it lmao
>>29082349Thank you anon, appreciate the insight.>>29082638Going to put in a 96 Vortec pump as an upgrade. I've already modded a tbi unit before so I will do the mods again. I will look into the cable, I was going to get a nerd off the internet at tbichips to burn me a new prom once I am nearly finished, I think I have the correct parts now, just waiting on the post office.
>>29082712need torque to tow a trailer, a 4cylinder will explode unless it's the GM 2.7 or whatever that POS is. I don't buy shit newer than 1994 anyway though.
>>29082004I'm keeping the engine block the truck came with, it's in good shape still. If it ends up blowing up down the road I will just swap in another 350 I already have or buy a crate engine depending how much scratch I have at the time.
>>29082712>just spend your life at 6,000 RPM to make the torque a ragged out V8 makes at 1,200....
>>29082797This anon knows machines.
>>29082797Ummm buddy that's 5 times as much horsepower lmao
>>29082805Give me torque and RPM figures for a K24 turbo swapped into a 5000 pound full sized K series GM truck. There are reasons nobody does this and instead spend a grand on heads instead.
>>29082809275hp on a K24 would be china turbo @ 7psi on the stock ECU sorta deal bud
>>29082810torque? Can you read? You a zoomer or something? I will ask AI how retarded swapping Honda engines into a truck is instead.
>>29082817I don't know if you're aware but there's things called gears and they will turn two completely different 275hp engines, with completely different engine torque, into the same wheel torque at the same road speed
>>29082834please tell me what RPM a Honda engine will turn towing a 7000 pound travel trailer. I have 3.08 gears. Also let me know if the engine will explode towing for 1000 miles every 2 weeks in the summer.
>>29082846Here you go budhttps://www.youtube.com/watch?v=gS4bHBCl7Sk
>>29082848So buy a new truck? Thanks for the help.
>>29082851it's a 2.4 turbo i4 towing near 7000lbsthat's what you wanted to know about isn't it?
>>29082856So buy a Toyota? Thanks Chang. You are obviously under 25, possibly 16.
>>29082859>I NEED TO KNOW WHAT TORQUE THE ENGINE HAS AND WHAT RPM IT WOULD BE TOWING AT AND IF IT WOULD EXPLODE STRAIGHT AWAY*provides information*>WHY DID YOU PROVIDE ME WITH THIS INFORMATION REEEEEEE
>>29082860>under 14. You need to be 18 to post here bub.
>>29082864>let me know if the engine will explode*engine doesn't explode*>NOOOOO DON'T LET ME KNOW IF THE ENGINE WILL EXPLODE
>>29082787Oh nice, I did the later 454 pump I think it's like 40psi or something but I'd do the vortec pump too. I'm sure they have a tune for what you have since it's so common. Even with the tune though it'd be good to have the cable so you can see the blm numbers if you need to pump the fuel pressure, and the knock counts since the stock motor expects 0 advance with the tbi heads, you can probably advance it much more with the vortec heads but I'd double check
>>29082930I put a k1103 in a stock tbi truck before and had to crank the advance to 8 or 12 or something to get it to run, I expect 8 degrees initial timing and going from there. I will for sure look into the cable as it would be great to have some data to review.
>>29082939Good stuff you seems like you'll alright.I think the cable was like 40 bucks or something, I liked the tbi so don't blame you for keeping it. I see more tbi stuff driving around than the later era ones
>>29082834>the transmission hes citing
>>29082978Buying a 2024 Toyota 2.4 and used Peterbilt to do a low buck small block build right now.
>>29082990Turns out that was too expensive. Was pretty busy today but did the cam and double roller timing chain. This truck will be much more reliable than a Tundra/Taco anyway.
>>29081854LMAO. There are 4 cylinder and 6 cylinder diesels out there that will smoke you. Imagine bus lengths getting pulled on you by a clapped Mercedes
>>29084032So? I'm trying to pull a trailer and need slightly more power than stock.
>>29084032Oh look, another one of these retards. Your type are almost as bad as doritotardsI have a 0.75L gas N/A that will smoke the shit out of anything youve ever driven.
>>29082710lb/ft isn't correct either, looks like working in "fabrication" doesn't mean much nowadays
>>29084569lf/bt
>>29084249no you don't buddy my engine will mogg your engine if we put them both in the same chassis
>>29084699He has a Kawisaki Sportbike or similar You ain't beating shit.
>>29084711oh wow what's that a whole 30hp?!
>>29084821Lol.Sub 1 liter superbikes were hitting 100+hp before you were born.
>>29085043This is a 998cc.
>>29085043Oh wow 100hp! That's less than a 1990s Toyota Corolla!
>>29085098>140hp/L is just like a 90s corolla...
>>29085139>ok ok ok so it WON'T actually smoke your shit>b-b-b-but at least it has good HP/L!!!!
>>29085160Dude, what?It will absolutely smoke the shit out of anything you've ever driven.Im sure if i brought up a SOHC or Hemi you'd cry like a little bitch about displacement or something.Take your poorfag cope back to /mlp/, faggot.
>>29082846>I have 3.08 gears.Holy fuck guy, go get some 3.73s put in that. I was on 3.08 too on my 351, new 3.73 makes a huge difference. Flat out better upgrade for your towing than the rebuild. But I'll be doing the same soon enough with heads and an RV cam.
>>29081854Okay boys we're officially posting in a troll thread
>>29085286my engine makes considerably more than 100hp lmao
>>29085399My gasoline smallblock hit 592hp on the dyno.Tell me again why I should give a shit about eurotrash diesels.
>>29085409lmao what happened to the 0.75L engine little buddy
>>29085438>t. only has one vehicleHave you ever thought about not being poor?
>>29085528>my 0.75L engine will smoke you!!!!no it won't>ok no it won't..... >BUT MY OTHER OTHER ENGINE WILL!!!
>>29085043>>29085045>bike that weighs barely one ton is faster than cars with more power(You)
>>2908561120 bucks says this dipshit has a 1.9 TDI (the only car hes ever owned) and has been sucking down the kool-aid since birth with zero knowledge of anything beyond what his masters tells him hes allowed to own.>1966 Mustang HiPo 289 with 271hp>1989 Mustang 5.0 LX with 225hp and under $10k (most hp per $ available)- Saleen was 290 from the same engine.>2012 Mustang base model V6 3.7L no turbo pushing 305hp.That was the cheapest and lowest trim mustang you could buy.
>>29085302The Summit heads were cheaper than getting my heads rebuilt. I could probably find some cheaper way of rebuilding the top end so I decided to add a bit more power.
>>29085769That makes no sense, I should rewrite it. Anyways I took the heads off because I had a broken exhaust bolt. They needed a rebuild as well but were cracked.
