is it possible to bore out a 3.0 and put 4.o pistons in it. or maybe put a 4.o crank in a 3.0. the whole point is more power. or does anyone know where to get higher compression kits or cam or anything for the 3.0

 

shave the heads.. it'll lower the Combustion chamber down to the piston more, and will bump compression.. thats what im doing

cam, go with a set of jusnes modified RR's

 

Swap your muffler bearings for the 4.0's

 

It would be less trouble to put in a 4.0, than to try to bore the 3.0 enough to fit the 3.0 pistions, and modify the block to have proper bearing positions to support the 4.0 cam. You should entirely forget the overhead cams.

If a 4.0 is what you want, get a 4.0, lol.

 

 

muffler bearings i heard that adds like 10hp haha. yah your'e probably right just put in a 4.0. im a little leary of swapping motors. last swap was a 302 in a 1970 mav that didn't work. how much trouble is it to swap the 4.0 in

 

Sell your 3.0 and buy a 4.0... It'll run you about the same cost wise and be a LOT less hassle

 

muff;er bearings? ok. lol

 

wow old thread, let it RIP
