72 Project

I am trying to decide which size to go with 502, 540 or 572. The price difference is a concern but I have some sway with the home finance official. If you are driving one of these why did you pick that CID and not one of the other 2.

Answers to anticipated questions:
1972 convertible original Big Block, 4 speed, car. No engine or transmission and has not been on the street or had a motor in over 10 years. The person I bought it from bought it without a motor or trans. I have a Tremec 5 speed kit on order and built a 370 rear end.

Thanks for all input

If I could afford a 572 that would be in my car.

Has anyone used this vendor? http://stores.ebay.com/whiteperforma...=p4634.c0.m322

If it were in my yard, I go with the closest dated, to the car, 454cu. in.

But that's just me. A BB '72 was a cool car just the way they were built. AND it's a convertible! WoWza!

Let's see some pic's, please!

Edit: FORT WORTH ROCKS! Love it

I also have a 72 that was an original BB car. It came with an auto and 327.
I went with the ZZ502 crate engine. I also changed over to a M22 4 speed. I was going to get a larger engine but where am I going. I am not going to race it. 502 HP is more than enough for the street.

I bought a 540..

409/409

White Performance on ebay, unless I overlooked it, has no place to ask a question or show where they are located or a phone number.
That would bother me before I'd flop down $12,000 or $14,000 or any amount!!!

572 is a tall deck engine. so exhaust and hood clearances will be a issue. a 454 or 502 from GM will be the simplest. the more torque the more your prone to break the rear end and half shafts. so the more cubes the more you need to spend else where

I'd look at all of the choices- I just built a 496, but I already had the block. If I had needed a block, I would have a 565--
A tall deck block seems to be a real hassle in a Corvette- header clearance, hood clearance.

joewill

yes 572 = tall deck.. which means a new hood, finding a body man to install/adjust/paint the hood, match the paint..
a 454 or a 496 ( a punched and stroked 454) would be the easiest swap from a reinstall/fitting of all your parts standpoint..

72 Project

Did you build it or buy it? How much HP and TQ? Do you have 1/4 mile times and speed? Is it a standard deck or tall deck? Details man. I need details. And a picture or 2.

Thanks

There is a place on the right to ask seller a question and it ships from Kingsport, Tennessee. and 99.5 percent good feed back. https://www.ebay.com/usr/skipwhite?_...p2047675.l2559

It says it uses a 9.8 Dart Big M block. I'm using a Tremek TKO 600 5 speed. The differential is completely rebuild using high end American parts 3.70 gears and new offset trailing arms. So the only question might be the half shafts?

The body is in rough primer and needs to be taken down to glass. A couple of small cracks and the wholes where the luggage rack was mounted needs to be filled. I have 2 L88 hoods. One with an air box and one without an air box. So paint and body will be in the future.

Also depends how sticky your rear tires will be. Your U-joints might fail and you might twist a half shaft. I wouldn’t bet the farm on the rear either.

Mr D.

If it was me I would go back 454 with a 4-Speed but I'm funny like that. If you're dead set on a bunch of HP I would put that bling money into beefing up the rear suspension or you will be throwing U-Joints and twisting half shafts.

I have a Skip White 427 SBC , Motor kicks *** .. High 10 second car and can drive it daily . 3rd season on it . Not a single issue and if and when I decide to go for more power his 632 915 HP big block is going into her.

Go to his face book page he is supposed to be making a video on his shop.

His equipment is top of the line.

I would go with the one set up for low idle,
off idle torque, and one that doesn't need to idle at 1k and feather the clutch.
depending on where you live, daily driving should be a pleasure not a
working effort to stop and go.
