These are excellent entry-level performance engines for older cars, trucks, and street rods. All of the parts in these engines are brand new.

Some members told me to get the engine rebuilt because I would know what Im getting but most of the shops that I have talked to wanted around 2k to do the work.

 

It is not an LT1 engine, it will not work in your application (as a drop in). Have your engine rebuilt.

 

Ask the shops who quoted you 2K for details on what that includes because it does not sound like enough money to do the job properly.

 

$2k is really cheap unless you're doing the R+R yourself and dropping the engine off at the machine shop.

 

That motor sounds great if you have a station wagon.

 

sounds like a 195 hp engine

 

dude- I've got my Lt1 for sale for CHEAP (complete). It's not a bad idea to get another engine to have rebuilt with the parts you want while you continue driving your car.

*edit*

I think a totally basic rebuild should be less than $2,000 (hyper pistons, reuse of the rods, crank). re-fresh the heads, etc/

 

im assuming the post is a joke because noone who owns and cares about a c4 would put in such a subpar motor.

In fact, even the stock motor is not adequete anymore.

the latest police cruisers (such as caprice ppv) will run circles around our c4s.

do a search on performance features. ported afr 195cc heads, long tube headers, 383 stroker, forged components, forced induction, etc.

may want to go a little lower compression in case you decide to go to forced inductiuon instead of being 'stuck' with high compression n/a.

 

Well- it boils down to a budget and need. If his c4 is his daily driver, than down time is a critical factor. For the "average" budget minded individual that just needs to get the car back on the road, a "freshening up" is good enough. Otherwise, it's easy to list "top shelf" parts... we're talking $10k plus for the little list that you put together.
