I've done a search, and no real posts. Who's got ZZ4's? I'm contemplating an engine swap and have no idea on what to get. I've got a 350 block, and I want fuel injection. I know the ZZ4's got a carb manifold, but I might be able to use my TBI on it. Who's got ZZ4's...how do you like 'em?

 

No one's got 'em??

 

Or what about this? I was searching around for engines, and this one looks decently priced.

If I were you I would build up a nice 383 with that 350 block you have. If you plan on making real power the TBI will have to go and a carb or high flowing FI will go in it's place. The motors you listed are GMPP motors. They're decent, but much more power can be made from a 383. If you did go with the 325 horse one, the cam would definitely need changed since it is rather small for large of a motor.

 

if you want to keep the tbi system I would get something from holley. check this out 1,500hp tbi system

I've got a stock ZZ4 in my 67' with TPI/MAF system and 700R4 trans. Has been running perfect for 30,000 miles. Great mileage (22 mpg). Excellent motor!
Lot's of power, but no traction, but still ran 13.59 ET one time out to the track with street tires.
