Just bought an 85 iroc with a 383. The guy says its pushing out 425 hp. Its got ***** but i dont know about 425. My buddy recommended doing a compression test to make sure im running stong on all 8 but i have no idea how to do that. How do I do a compression test and what do i need to do it?

 

you need a compression tester, available at any parts store, all you do is pull the plug wire and plug out of one cylinder, install the tester and get a buddy to crank the engine over. also disconnect the coil wire so the engine doesnt start, you should see around 160psi if its a good engine.

 

How much did you buy it for?

heres one, i think. i didnt know you could buy these at autozone. lol. not expensive either.

 

It's possable to have that in the 383, but thats at the fly, you may see about 375 or more to the wheels. what all does the motor have and what is hooked up on it?............and got pic's, not as proof, just a bunch of pic junkies here.
