Is this possible any huge changes and what would be needed if I had 4v heads?

 

I think low end might suffer while top end goes up. Don't quote me on this though.

 

I was thinking the same as you were about low end suffering a bit. I'm looking to maybe do some mods like that, but modular engine seem like a whole new ballgame compared to small block chevrolets. I'm looking for more power and torque without the usual bolt ons

 

Well 4 valve heads wouldn't net you that much power to begin with. Not enough to justify the price. If you were planning on adding a blower to go with the heads, then you would be making some serious power.

 

yeah im just trying any mods right now. i have programmer, exhaust here soon, cai underdrive pulleys, have an efan setup (just havent installed it yet). im looking for anything to net me a lil power. what about bigger injectors? im grasping at anything, but dont wanna supercharge or turbocharge it yet, can't really afford one of those, plus id like to do a complete engine rebuild with heads, pistons, and cam before i force induct the thing..

 

just spray it and blow the engine you have now, then do a 4v f/i swap

 

lol id spray it if i knew it wouldnt blow, but i cant afford to do that right now.
