hey, now thats an engine. Looks great.
Two questions, What make are those headers and what size tubes do they have?
I am always on the look out for any information I can get on a BB in these trucks as I am building a 454 for mine.
Once again, that looks great. Keep us updated on this one please.

I went with the Flowtechs with 1 3/4" primary tubes. You have to grind off some of the flange on the underside of the header to get them to fit over the head bolts on the 502.

**Yukon Jack** · 02-10-2003, 05:55 PM

That looks awesome!

**1971Stepside** · 02-10-2003, 06:03 PM

That looks great! I have a couple questions for ya since you are setting yours up very close to what I have in mind for mine.

1. Did you use 72 BB stands? If not, what did you use?
2. Did you buy your chrome alt/ac from Zoops as well?
3. Who's product did you use for your fans?

I'll be saving these pics for motivation to save the big bucks for the ZZ502!!

72ChevyCheyenne · 02-10-2003, 08:05 PM

The stands are from a 71 with the 5 piece mounts. The alt is from zoops and the AC is from Vintage Air. The fans are Flex-a-lite.

Project1970 · 02-10-2003, 08:14 PM

What tranny is that?

spinning wheels · 02-10-2003, 08:33 PM

What is the difference from the '71 big block engine mounts to the '72?
Just starting my BBC project and need to get as much info as possible. Thanks.

72ChevyCheyenne · 02-10-2003, 11:35 PM

Project - The tranny is a built TH 350

Wheels - Below is a pic of the towers. The one on the left is pre 72 and the one on the right is a 72. The pre 72 towers are cheap but the mounts are expensive. The 72s are expensive and stronger but the mounts can be purchased at any parts house.

69 Short Fleet · 02-11-2003, 05:08 AM

Hi 72 Chevy: That is beautiful !!!! I have a stupid question, do the 502 crate motors come with aluminum heads and what kind of valves (stainless)? and is your block aluminum also? I don't know that much about them, thanks Doug

72ChevyCheyenne · 02-11-2003, 08:19 AM

The ZZ502 comes with aluminum heads and cast iron block. The valves are 2.25" stainless steel on the intake side and 1.88" on the exaust side.

70c10 · 02-11-2003, 08:34 AM

Very nice!, Bet ya can't wait to take that bad boy for a spin!!!

**1970 CST Short Wide** · 02-11-2003, 10:46 AM

Next ? Does your engine set back farther with the BB and did you have to shorten your drive shaft ?

72'BBGMCSGCC · 02-11-2003, 12:39 PM

I want to do the same to mine .It's going to cost about $2,500 to rebuild the origional 402 and I was wondering How much has the project cost so far if you don't mine me asking. so I can compare the price difference. Thak you

**1971Stepside** · 02-11-2003, 01:09 PM

I can't speak for 72Chevy on his cost, but you are looking at about 10 grand worth of stuff there in those pics alone. A new ZZ502 is around $7200....add the great things he has like the chrome alt/ac/pulleys, fans, built TH350 and it doesn't take long to add up.

72ChevyCheyenne · 02-11-2003, 03:03 PM

70c10 - You are righ about that, I can't wait to just get it started much less drive it.

1970 CST Short Wide - The engine does set back about an inch. I had the shaft shortened and moved the tranny support.

72'BBGMCSGCC - 1971Stepside is about right with the 10 grand cost. I have not sat down and totaled everything up yet. I'm almost afraid to at this point. Everything is new except for the frame which I had blasted and powdercoated and the steering box which was new last year. The 502 was on special through GM in November for $6800 and the Zoops pulleys and brackets with power steering pump and remote tank was around $800. I figure I will end up with around $20,000 plus by the time it is finished. If everything goes as planned I will have it at the Chevy/GMC Truck Nationals in Pigeon Forge the first weekend in May.

**1971Stepside** · 02-11-2003, 03:49 PM

Yeah, don't total the receipts up until after you are driving it again!! LOL

**1970 CST Short Wide** · 02-11-2003, 07:10 PM

When you say you moved the tranny support did you have to drill new holes or where they alrweady there?

72ChevyCheyenne · 02-11-2003, 09:03 PM

I drilled new holes in the crossmember.
