Thread: 383 Stroker For My CJ7

Tweet

I currently have a 80's model chevy 350 in my jeep. I want to build a mild, reliable 383 stroker. I have a few questions about this process. My jeep is a frequent street driver and some woods riding.

I have seen several 383 stroker kits on the internet can anyone suggest one or recommend. The kits I have seen usually include the complete rotating assembly.

My questions what is going to have to be done to the block? Do I need a new intake and or Heads? I currently have a stock 350 with cast iron parts. I appreciate any information.

Spend your cash fixing up the 350. Stroker kits are the most expensive way to get horsepower, and not worth it for your application. If you really want cubes, why not find a 400?

Well the 350 only has about 500 miles on it. I would also have a problem fitting a 400 big block in my jeep without major mods. I am just trying to find the best way to make alittle more power to the 350.
thanks

400 is a small block. A 350 with low mileage like that will come alive with a cam and a hirise.

Sounds good to me. Just a mild street cam Like? Can you point me in the right direction? Hirise? No IDEA. Thanks for the info..

High rise intake manifold.

Really in a Jeep a high rise is the wrong thing to do, but I agree with keepng the 350, 383's have a lot of problems if they aren't professionally built with very careful parts selection.

On the intake stick with something like a Performer. on the cam select one with about 112 LSA, around 270-276* of duration and abot 470-480" lift.

This will really wake a stock low compression 350 up without making it unmanageable. You don't want a highrise or large cam b/c you will lose the low rpm Tq that you need for climbing hills slowly.

I agree with Bidwhale. The Edelbrock Performer intake is a good one for your application. I think I'd even step down a little on the cam since you go off road with the Jeep. I'd suggets looking at Comp Cams, 262 Hi Energy cam. I've used this cam in several SB Chevy pick-ups and had very good luck with them. Lots of lowend torque.

Also stay with a carb no bigger than 600 cfm, such as a Holley # 1850 or the Edelbrock #1406. Also a set of small tube
(1 1/2- 1 5/8 inch) headers will help.

Also consider recurving your distributor. If it has the correct initial timing, the correct advance rate and total timing it will make an engine a pleasure to drive. However, that usually isn't the case and your giving up a LOT of lowend torque and horsepower.

Initial timing should be about 12-15 degrees BTDC.
Total timing should be about 35-38 degrees BTDC @ 2800-3000 RPM.
The vacuum advance should be limited to about 10-12 degrees and start to drop out at about 12 or 13 inches of vacuum.
Don't spend a lot of money on a fancy distributor. The GM HEI unit will do everything you need.

I hope some of this helps. Have fun.
