3.4 hybrid

I am looking at buying a 88 RS

its all black, chrome mags, ttops, perfect interior and decent paint. THe only thing that bothers me is the engine
its a 3.1/3.4 hybrid. He said he kept the 3.1 block, put on the 3.4 heads, etc on from a 93ish firebird with about 30k on it. The cars been sitting for a few years, said it runs prefectly fine just needs a fuel pump

is This engine reliable? how fast is it?
also, is this car worth 1200?

I own a 1989 cavalier convertible with a swapped in 3400 from a GAGT, as long as its faster than this I'll be happy. Anyone know what kind of HP this engine would push? Thanks

All of the iron heads are the same no matter displacement. So really you have a 3.1 in your car. I believe that he 3.1 only put out 140HP stock.

Re: 3.4 hybrid

jesus, thats a lot slower than what I was hoping for. My car with the stock 3.1 was not fast enough for my liking

I may have to reconsider this, thanks.
Also, how reliable are these, and is this a good deal?

I paid $2600 for my bird 1yr ago with 89k miles (only has 89k now ). Did 17.1 @ 75mph in the quarter bone stock and 17yrs old. The question is: "Is the car worth it to you?" Click on my garage icon under my username to see what I got.

Re: 3.4 hybrid

No way in hell a genI 3.1 will be quicker than a J-body with a 3400 swap. Most 3.1 F-bodies run somwhere between a 16.9 to an 18, that I have seen.

A stock 1st or 2nd gen J-body with a stock 3400 swapped in, untuned will get between a 14.5 and a 15.0.

You could always, build a real hybrid in the F-body.
