trucks are heavy and 350s are not that big,,,experience helps when tuning.
I bought a 1980 Camaro off a younger fella,right parts,LS-5 454,headers,car weighed 3915,his best times were high 13s.
Cost me 3k to run 11s,just fixing his mistakes and upgrades

|vinniekq2||If you want to run low 10s/high 9s in the 1/8,then use the 350 and 4.1 gears|

4500 pound truck is not going to launch hard without a lot of gearing/traction and hook.
If you get all of that,its also going to be a parts breaker.
I would consider building a 380 hp,,500 # torque 454 that peaks at or just over 5,000 rpm.This will be easier all around.
Basically an LS-5 with mild cam,headers,good 4 barrel and intake

|Slammedsi||Motor will be in a 4500lb ish Chevy truck. 1/8 mile track several times a month and the "When I'm bored" trip into town in the evenings. Also there is a large car show and drag on the main road through town i would like to attend with this setup.|

Thanks for the help guys. I was planing on going single plane and keeping it under the 6500 rpm mark. If there is doubt that the rods would handle something like that then while I'm there i might as well do it right.
Maybe go with something like the Scat engine kit that has the full rotating assembly. Like this one, But this one has Hypereutectic pistons.

|vinniekq2||to make 1.5 hp per cubic inch,I see decent solid roller cam,over 10:1 CR,single plane intake,850 CFM carb,heads that flow 300 ish cfm,1 3/4 primary long tube tuned headers,maybe even stepped headers,drive line parts to take the power,suspension to plant the power|

Sorry, That casting number is correct. I was planing on using the Block, Crank, and factory rods. Along with a set of quality forged pistons and aluminum heads to get to the 10.75:1 - 11.0:1 compression mark, running a mix of 91 and 110 octane fuel.
Does anyone know what the factory rods and crank will handle horsepower wise?

Sorry, but that is a low compession smog engine. It will take big bucks to get anywhere near the HP you are seeking. I build 327s for C2 vettes and 383 strokers for the high horsepower seeking vette guys. In Cal that is 73 and earlier, non smog controlled engines. Anything goes and is legal here on 73 or earlier cars. I just built an aluminum headed 383 stroker engine for a friends 65 vette. It dynoed at 437 RWHP, that is over 500HP at the flywheel if you take the 20% drivetrain loss that is the norm. The car has a 4 speed and 4.11 gears in the rear. To back that up we took the car to infinion raceway, as a noob he ran 12.5 in the quarter on the first pass. No tire burning or speed shifting. Just a lazy take off when the light turns green at an intersection.
I have a pantera, a go kart on steroids. at 100 mph the end would lift, the hall air dam solved that. At the same time the rear would lift. the wing on the rear deck solved that.
Sorry, But why a pickup, It,s light in the

|vinniekq2||If you want 450 RWHP then all you will likely use is the block and crank|

Ive got the casting number wrong i guess. When i looked up the code it came up as a 77-79 Nova and other cars.

Small Block Chevy Engine Block casting and code identification

Understood. I believe the block casting number is 14016379
