To much to say but if I was guessing not knowing your skill I would say low 14's to high 13's.

 

i originally had a 305 with just exhaust no headers. i will notice quite a bit of difference right?? i know there is a guy on this site called z28boy who has the same setup and he said it was a night and day difference

 

You should pick up a second or so in the quarter. 13 or 14's. The 305 was probably a 15. I know a guy that had that engine in a 81 2wd pickup. He was doing 95 mph. He put it in his 80 bird and hits about 100 mph. He has a 2.73 rear with a TH350. You'll probably be in overdrive when you are done the quarter mile.

 

Keep us up on how the 330 HO works out for ya, considering that swap myself.

 

You really think he'll be in overdrive by the end of the quarter?? My 81 Z28 has 3:73 posi with a TH-350 and a motor with ~350hp and it isn't topped out by the end of the quarter. I can top it out in third gear too. Guessing it to be about 130mph at 6000rpm. It does have a stock converter, however.

 

Not to mention, it probably wouldn't shift to overdrive if you were running a quarter mile. That is unless the Raptor 700R4 is modified to fix this.

 

i will keep all of you up on the swap i believe it will take about another week and a half to two weeks. the guy who is doing the work told me it will run like a brand new car when he's done with it im negoitiating on whether to put a new aluminum driveshaft and a new radiator in it to keep it cool. im going to school in miami next year so i want her to stay cool (she's my baby!!) hell, she's hotter than my girlfriend j/k
any ways would i need a new cooling fan to if i decide to do this?? if so which one?? single or dual?? what model?? anyways thanks guys
