Thread: building a 383 stroker

Tweet

Hey guys,
I was wondering if anyone out there could help me with a brand new build of my 383 stroker? I Pulled my 350 4 bolt main from my 67 el camino, disassembled it and had it machined to a .40 over. Right now Im trying to figure out what rotating assembly to buy along with a cam and heads. Here's what my goal is. I want to build a motor that kicks me back in my seat when i punch it and takes off (It would be nice to put my snotty neighbor with his souped rice rocket in his place). I have a 700R4 race tranny to go with it. Im obviously looking for the horsepower and even more looking for the torque. obviously there are plenty of kits out there I can buy but my dilemma is I would also like the car to be practical. I plan on driving it 60 miles a few times a week round trip to work and back. At this stage in the build I need to buy a rotating assembly. any suggestion on a good quality kit I should buy? Im not looking for a compression of 9 or 10 seeing that I want it to be practical. goal is to have horspower and torque in the low 400's. Am i crazy or is this possible?

First, welcome to CHR! You can buy a crate engine from Summit (just the first one that popped up) BluePrint Engines BP3834CT1 - BluePrint Engines GM 383 C.I.D. Stroker Base Crate Engines with Aluminum Heads - Overview - SummitRacing.com with 420hp/450TQ so you're not crazy. We've got several guys on here who can walk you through the pieces/parts, or you might search for some old threads where it's been hashed before.

I am not big on package deals mainly because there is a reason why it is a "deal" with some weak links in the rotating assemblies.I have spent tons of time looking at that and know that is the case.
For the price of getting a 1996 or later L31 truck block(tons of them out there cheap)it's hardly worth paying for the very expensive hydro roller cam conversion kit for a earlier block.You do want to take advantage of the hydro roller cams for their cam profiles for one,along with so many other features.

This thread although long,is my build with three of the most knowledgeable people this site has.Your going to read twists and turns and some paper errors I made in calculating compression ratios to come to what I believe is a solid well thought out build.

383 build-Something Caught My Eye

Go for AFR heads: take a look at the dyno-tested combinations on their website. You don't need a huge cam to make awesome horsepower and torque. And your car will be happy on the street. I used the 460 hp combination as a model for my 383.
