Scott - Good for you! I am putting a 360 out of a 77 Matador into a 74 Gremlin. I think your HP will depend on your compression ratio, cam, carbeurator, etc. If you want to just drop in the 304 without reworking the engine, I think you can probably expect 200 - 300 HP, depending on if you keep A/C, PS, etc. I took mine apart and had it completely redone. I hope to get 350+ HP when finished. Good luck - it sounds like a wonderful find! -Lu- --- In BaadAssGremlins@xxxxxxxxxxxxxxx, "blue77gremlin" <blue77gremlin@xxxx> wrote: > Hey guys I found a 70 Matador 4 door with 50k and a 304 with auto. > The body is in bad shape but the owner said the motor is real good. > I was wondering if this motor and trans would swap easy in a > gremlin.
