Engine Combo Questions

do not go to j-heads or x. they are old and over priced. You can go to mopar commando heads (big port) or to stock magnum heads or magnum r/t heads.

car craft got 400hp from a 318 using the stock magnum heads no porting of any sort, imagine alittle porting and putting them on a 360?

any ways go to the junk yard and pull off some good heads, intake, all valve gear, head bolts, pushrods (if you can find a 360 block that used a roller cam, also the lifters) tb, flywheel, pcm, and harness. do some mild porting and blot everything on to the 360 with the formentioned pistons.

you will have more horsepower than the other heads plus way more perfomrance and cheaper! plus have efi! you can get everything at the yard for under $200. and j-x heads are over $500 atleast!

you could even get a 318 and get your goal hp range. a 318 is a 340 with 20 less cu.

if you want big cubes you can with a 4in crank with stock rods or scat h-beams for $300 plus diamond pistons $500 (forged!) and use the mentioned parts and make more power than the 360. and if you wanted to you could at a supercharger form the superchargerstore.com and make 650hp atleast on pump gas!!and no loss of gas miliage! Of course you will have start upgrading other things. Chassis wise.

so in closing the magnum heads are the best choice as you can use chevy crane rockers which are way cheap.

if you want to stay carbed. mopar makes a magnum heads that uses a la intake.

good luck
