Hey Y'all! as you can tell from the title I'm getting ready to build my first motor from scratch. I've got the block and even better ive got my mechanic friend ready to check my work as I go. Now here's the hard part: learning what to buy. The block is a 70's era 454, pretty good shape. I...

My engine is finally going together and I’d like to hear from some of you more knowledgeable guys what you think the hp is going to be. Here's what I’ve got: ’94 351W with a stock deck height of 9.503. Squish/quench is .066. ProMaxx aluminum heads with 60cc chambers, 2.02/1.60 valves and a...

I have a 87 Monte Carlo LS with what I believe to be an HO 305. The reason why I'm not sure is because it's made of so many different car's parts. Not sure if the engine is stock but the head's casting was 081 so I assume it's an HO. From research I found that it's an LG4 which was machined for...

I know I've posted a similar thread in the past, but a lot has changed with this motor since then. If anyone would be able to provide an estimate of the horsepower and torque this engine will produce that would be awesome! This is going into a 1978 GMC truck with a TH350 w/ shift kit and 3.08...

I have a bone stock 1980 vette with a SBC 350 and a 700R4 transmission. The car is slow as snow and i want to make it faster, but i dont want to piss off my wife and neighbors from the noise of a super loud engine. I have spoken to a local performance shop that said they could stroke the engine...

Alright so I've been ALL OVER the internet trying to find a good answer to this and I really haven't come up with much. How do you find your secondary jet size (with max HP in mind) on a traditional Vacuum Secondary Holley 4 Barrel without an AFR gauge or a drag strip to evaluate E.T.'s and...

I found out that I have a 383 in my 79 Camaro. I was wondering what type of horse power I would be making and if I switched from 76cc to 64cc heads would do. The engine is a 1970s 350 bored 30 over with flat toped pistons. Forged rods and a 400 crank with a push on harmonic balancer. It has a...

Hey all, I was just wondering if anyone has a HP estimate of my motor? It's a 350 with stock crank, rods, pistons, and bore. Piston is about ".024 in the hole.

Hey HotRodders, I was on here earlier looking up how to build the cheap made in mexico 350 V8 and seen how big the gain in horsepower was with the ported Vortec heads, intake, and Holley carb. I realized that i have a Vortec engine thats in great shape so ive decided to build this...

Hi All, I regularly see engine ratings for the same or similar displacement engines with varying horse power and torque ratings depending on their intended use. Some engines are used in towing/hauling applications, thus having lots of torque (trucks, SUVs, mini vans). Others are used in...
