Tell me about this SBC
 
I was shooting the bull with a good friend, and had mentioned that i was wanting to locate a good short block sbc to stach away for a later build. Of course he happened to have one. I cant seem to locate where i put the block casting numbers but it do remember what it came from. It showed to be a 77-79 Motor from a Chevelle, Camaro, Nova and a few other cars. He states that its been on a stand for some time. Very honest guy. He wants 150 for the motor and its from the carb to the pan. Would anyone happen to know what kinda compression this motor would be? I will get the block and head casting numbers in a day or two. Im looking to build this motor with quality parts to make somewhere around the 400-450 WHP mark in a 77 C10.


Edit: I believe the block casting number is 14016379.

We need some casting numbers to start with that is a tall order HP wise.

Understood. I believe the block casting number is 14016379

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

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

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?

It really depends on how high you plan on winding the engine. I'd feel comfortable going to 6,000 rpm with factory rods if everything is built correctly. After that it gets a little shaky with stock rods.

vinniekq2 04-03-2013 10:26 AM

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

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.

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.

vinniekq2 04-03-2013 11:29 AM

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

Ive got a B&M street/strip TH400 already, Was thinking about a set of 4.10's for the rear in a 12 bolt instead of the 10 i have now. Ive looked for a 454 in the past with out much luck. The ones i found needed a lot of machine work or was way over priced. I felt it would be best to build this motor, as it only cost me 150.00 and he helped load it!

vinniekq2 04-03-2013 01:31 PM

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