Hi Guys, Looking to beef up the motor in my '85 Trans AM from an 87 TPI 350chev crate 290hp, and wanted to know if this combination would work well together and give me the power i want. Transmission is a t700r with stage 2 shift kit built to handle 700hp, stock TQ converter. I'm lookin to get the following parts to get the gains i want: 383 Stroker kit off ebay: http://cgi.ebay.com.au/NEW-CHEV-350-...3A1%7C294%3A50 AFR 1040 heads complete from thunderracing.com 63-08-466-8Comp Cams XFI Camshaft, 218 / 224, .570 / .565 113 LSA and a complete Holley Stealth RAM kit with 36lbs injectors Have I left anything out that i will need (other than gasket/rebuild kit) or anything which will conflict or not work with what i have/want?

I am not sure what you have available in Australia, versus here in the states, but personally, I wouldn't trust Procomp in a rotating assembly. I've seen some of their ignition products, and they weren't so super. Cheap as hell, yes. But in more than 1 way.

Stick to the major rotating assembly companies if you can. Eagle, Scat, etc. Those 2, especially if you're on a budget. Their cast line would be plenty adequate to survive the power levels you're after.

You're going to want to invest in a high quality stall converter, with a higher stall speed. Determine the required stall speed once the engine specs have been finalized, but expect in the 25-3000 range.

HSR and AFR heads are solid. And I am a big fan of Comp's XFI line. Don't know if you'll be at 500 or not, but it will make for a pretty good setup.

I'd guess closer to 450 hp, and I suggest going to the next-larger cam.
