Anybody running lower then 12s QM?

[INSIDIOUS '86]

It seems that 12s in our trucks is using motors that usually have passenger cars doing 11s.
Weight and aerodynamics play into our factors here

A fiberglass hood and a tonneu cover can help a lot as well as just getting rid of meat all around. Our front "girder beam" suspension is built to destroy anything it hits but is also a good 250lbs! Our bumpers and hoods are silly heavy and the tailgate is 80lbs itself. No consider we are shaped like a brick hous or the side if a barn. The odds are against us. Our engines have to be bigger and stronger. A chipped newer silverado will give us all a run for our money these days.

The squarebodys are heavy, but not as bad as I would have thought. My 85 longbed weighs 4020 without the spare tire and about 5 gallons of gas in it. Iron head smallblock with a/c, and all the other accessories.

dang. then our rigs from short bed to long shouldnt have that big of difference

200r4 are not the same as 700r4s. I have seen too many 700r4 issues to even consider running one(personal experience). The amount of money it takes to get a 60e up to the task of handling big power is better spent on a 80e in my opinion.

[softballnrd27]

I like the way you are thinking. Yes they bolt up to a th350 just fine, I have done it in my truck.
My advice is to look for a 2004 or newer iron block because they came with a little bit better rod. If you are going to replace the internals then it doesn't matter what year.

Yea did some research on these a while back with the only truck engine LQ4 6.0 liter LS that stood out at me. i like how everyone was putting them in front of Th350s and bolting em right up. Hell with these cubes, and the old 350 block out, certainly even carbed and iron heads, right out of the salvage yard should have some really good pep stock, and then when i do my LS3 head swap and turbo it should be pretty nice

A 6.0 is 366" a 383 would be less $ and fabrication

i just found me a LQ4 all together for $450, another for $650 at the same salvage yard near by out of a Silverado 2500 series, not bad

[softballnrd27]

A LS swap is on par as far as $$$ with a 383 build.

[KQQL IT]

The engine yeah.
But i was thinking accesory drive, ignition and related bits and pieces

idk sometimes you can score big on those. you never know

[flamingbig10]

mines a baby cam lq9 with full bolts and tune 373s makes 370 to the wheels and runs roughly 12.7s with a very tight stall on drag radials, I will be running a 4000 stall cal tracs, slick and 150 shot should bring down well into the 11s

running an LS with all bolt ons? and getting that? sounds like those hotrod magazine gurus werent right about 500 hp at the fly wheel with just a cam swap, dang , id try 2500 stall, with balloon plates, make sure it has those plates, some converters like to come apart with the nitro or other sorts of boosting on N/A Engine

[INSIDIOUS '86]

Should do one mid at a Tim for us so we can see what starts making the biggest difference. Other than tho nos fogger...

i could see 500hp with cam and heads, a 2500stall would be way to small

[INSIDIOUS '86]

A 3000 with lockup would be just right lol

I went 11.82 in the truck in my avatar. Its a 496 with a set of mild ported 781's with, stock valves. It has 10.3 comp with a solid flat tappet cam and a gasket matched 70's torkerII and a 950hp. It also has Hooker super comps and 3" side exit exhaust with 40 series flowmasters. I'm running a TH375 with an ATI manual valvebody and a Jeg's 10" 3400 stall converter. On that pass I was running a 10 bolt with 3.73's and a rebuilt stock posi. I'm getting a 9" together with 4.11's a detriot locker for 35 spline axles. I have 275/60/15 BFG drag radials on it. With the 9", I'm going to put 325/50/15 M/T drag radials. I've also got Camaro coils in the front and, I cut out 4 of the 6 plies on the leaf springs. I also made up my own caltracs too as well as, Comp Engineering drag shocks at all four corners. I don't understand why some of the guys in this thread are saying that, faster than 12's in these trucks is crazy. My truck was very stable on all of the passes I made that day.

Not with a big block! That's easy. But making a sbc do it and be Daily driver as well. Just a lot tougher

Nobody specified at the start of the thread!!! It is easier with a big block though. The best I got out of my sbc was a 13.25 @ 104. That was the same suspension set up and rear too. It was a mild .060 over 350 with, Vortec heads and(I know I might hear about this) a big mutha thumpr cam. But, I got the best ever passes with that cam! But, I wasn't expecting an 11 sec pass that day. I figured low 12's. On the 11.82 pass, it spun the tires when I hit 2nd. So, hopefully with a few tweaks, I'll have an 11.50 truck. Eventually, I want to get it into the 10's and be street legal. But right now, its really streetable. With, the exception of the fuel mileage of an almost 500 cube big block.

Hey I have the small thumpr in mine. It's a great cam for anybody who wants the sound power and drivability and brakes. With most other cams you can only have two of those. Just idiots buy them then hate them cause they think a half inch lift cam is going to work well on factory small block heads...no.
But it was never specified but since the original poster has a sbc I figure the thread may be better suited to sbc related stuff

I think the real the real issue is the line that while not thin but def not big is getting our bricks to do lower than 12s and still be what they are, a truck. I mean lighter smaller camaros and mustangs older Vettes and such. 450hp and your there and grandma can still drive it if your combo is good. For our trucks about 550hp is needed or 500 and a well thought setup.

So while today's tech has certainly made this possible in a sbc and a bbc can do this with ease I think we all know its easy to do 10s with our trucks and we all know basicly how to do it. Not hard to figure out that big meats a good rear susp and big motor and being stripped will get you there. But doing it and being street able esp with a small block. I think that is what maybe this thread should focus on and some bbc too cause we love em. But hey who here can say tomarow they are just going to buy an ls7 for 12k tomarow and throw it in? Not very realistic now is it?

i comend you for dropping a 8.1 liter in your square, are those castings for EFI vortecs on the big blocks or old school? insidious, he is right, i think it would be easy to take a nasty small block and turn our arrow dynamic bricks into rockets, but intill then i say the big blocks are allowed, not many small blocks running the street in our squares touting less than 12 second passes, not to mention the all stock part. so yea much of what you and i are gonna hear on this thread post is gonna be sick, nasty small blocks, and BIG BLOCKS!

[flamingbig10]

ls motors like loose stalls

Cool truck.
