was the big block swap worth the trouble if not can i get some info if i should stick to the 355 or should i go to a 427 big block let me know guys i know yous are gonna say search and i already did and came up with pretty much nothing what was needed to swap big block in?

 

I ran a 468 BBC in my 85 T/A. It was on alchahol with a powerglide, and transbrake. Used a "Rons" injection system, it ran very good. The engine was pretty tight, we used the Hooker Super COmp headers. Heater a/c box was removed, booster was in the way though. The steering shaft was close, had to trim some of the car to get the headers to fit without binding.
The best it ran was 9.21 @ 148 mph.

 

What do you have and what do you want? What's your budget? What are your goals (power, handling, fuel economy)? How often will you drive this car? What are your emission requirements?

These are all questions you need to ask yourself and answer. My personal opinion is stay away from the big block swap. Unless you simply have a need to say you have a big block under the hood it's not worthwhile. It would be cheaper to use an old Chevelle with a big block.

 

Hey, I dropped a 396 with a 400 Turbo into my old 87 IROC T-tops. Heres the surprising thing, it had no subfame connector and never twisted once. And this was a pretty strong 396, mild cam, Performer intake, 850 carb, pretty powerful motor being mostly stock but it connected well. The swap mainly consists of you making some serious room under the hood, so say goodbye to all the usless wiring and as for power steering, you'll have to buy a custom setup. Also, as for the crossmember, you'll have to buy one or make your own, which is what I did and it never gave me trouble. But one thing is, you'll most likely have to go to an electric fan, because with my electric fan, it was still pretty tight. Well, hope it helps ya.

 

isnt the subframe connector the thing that keeps or t topped cars structurally straight, die to the lack of hardtop??. i know the droptop fbodys were based on the t topped ones becuz of this structural support
