first and foremost, a tall deck big block will be a tight fit. Do-able, but not fun to work on AT_ALL.. Like spark plugs being worse than you can imagine..

For the street and occasional strip use, I would choose a short deck, big cube big block.. 10ish-1 compression, and throw the juice to if on the strip.

We had that 540" Shafiroff "Ultra Street" motor in my car, it made 728 HP on the brake, with an 1190 King Demon carb, but we converted it to EFI and it ran 138 mph @ 3500# in my car.. Pretty stout to say the least- and that was basically untuned- hell it didn't even have a MAP sensor, but that's another story..

We took that same 540 and put a single stage big shot plate system on it, (dry) and ran a 5.33 (600') at our local track on drag radials with a glide but the car still weighed 3380#.. It would go 5.50's in a true 1/8, and there's room for more nitrous..
And- this was done through a set of hooker 2455 headers which are almost a perfect bolt in with a tubular k-member

I went with a Dart Iron Eagle small block, short stroke, big bore, thumper turbo.. It doesn't make for much of a fun street car, but it's faster than the big block

Cliff notes: big bore 9.8 deck big block is a relatively easy fit and will make a super fun street car.. Nitrous to be low 9's at 4000#

good luck, and drop me an email if you have any specific questiojns.. We're putting a tall deck 572 in a '94Z now..

1. What K-member did you use?
PA Racing

2. Did you fit a manifold under the stock hood or use a cowl hood? What manifold did you go with?
Cowl hood, have to notch the cowl, but you can keep the wipers. We used a Vic Jr. intake, converted to EFI by Force

3. Did you keep the stock PCM to run the gauges?
The PCM isn't required for anything except the speedometer. I used to have it in my car, but it didn't make the last round of weight reduction. I still use the rest of the stock gauges though

4. Did you bother with any kind of cold air intake or just draw from under the hood?
Let it draw from under the cowl

5. What distributor and were there major fitment problems?
MSD Crab Cap distributor and a crank trigger. No problems at all.

6. What did you for an exhaust? You already mentioned the Hooker #2455, but what about the rest of the exhaust?
3-1/2" Dynomax race magnums w/turndowns.

7. What tranny are you using? I'd like to just keep my Rossler TH400.
Used to be a TH400, but switched to a glide. with a 4000# car, you'll need to stay with the TH400.

Thanks very much to anyone who can help with these questions. I will also email to Brady.

That's basically the way I started out... but then the NJ "mobile emissions" inspection shut me down as far as street driving, and now I'm sort of "stuck" with a car I can't really drive on the street - even though it would pass rolling emissions, and isn't fast enough for the track.

For a street driven car, I would think the SBC would be a lot more manageable than the added weight of the BBC.
