My wife and most other people call me the cheap Italian. And for good reason. Lets assume that 400Hp is plenty. It is by the way. 302 inches at 400hp is 1.32Hp per inch. This would be considered by most people as a healthy street/track day type motor. Additionally your AFR's ,165 or 185s, will easily support 400Hp and 6000 RPM's is enough revs to achieve 400Hp also. The 205's are a bit much for a 6000 RPM limmit and 302 inches. If you have them then go for the stroker and a main girdle. Plan on at least another 50-75 Hp over a 302/185AFR's.

Another consideration should be type of cam. Not specs but type. Solid tappet, roller tappet, hyd tappet, or hyd roller. With a 6000 RPM rev limit it doesn't make much sense to go a solid route either flat or roller. Both of these would be necessary above 7000 and surely the roller's would be needed above 7800ish. 7500+ PRM motors typically are at or above 1.6 hp per inch or about 500 hp(1.65) Since you only need 400 I would say stay with quality hyd.roller valve train parts. Crain makes several nice complete kits. I would stay with the same manufacturer for both the cam, roller lifters and springs. Makes life simple.

10 to 1 CR is also on target for 400 hp and 92 octain street gas so you are good to go there. So back to being cheap. Tear to whole thing down. Have a good look at the block and if it is good, clean it up and use it. Same with crank and rods. Use VERY high quality fasteners, especially the rod bolts, and get the best shop in your area to balance it all for you. Stock new oil pump, nice baffled pan, eldendbrock victor junior alum water pump and you should be all set.

Note. With your 6000 RPM limmit and power output in the sane range you shouldn't need a main cap girdle or new rods. But if you feel the need then both won't hurt too much. I don't think you don't need a big dollar block or crank at 400/6000. DO use a quality dampner. I really like ATI's or TCI Rattlers.

Note 2. FMS crate motors are not balanced beyond what stock production 302's are. If you buy a crate motor from anyone else ask about balance specs.

Have fun.
