1980 Vette top end build Q's

Well starting to look into getting the supplies rounded up. I've talked to quite a few people locally and surfed the web and I realize everyone has what they like. Basically I have a stock 350 (190hp) loaded down with miles of vacuum hoses , AC crap & smog junk. My plan is to lose all the ac & smog components (exhaust included) and just leave what I need to run the lights, brakes and what not as far as vacuum. Thinking that will free up some space,drop a couple hundred pounds and free up some hidden hp all at once. It's a win win on that topic !!!

I plan on using the Edelbrock 2099 top end kit.
Headers , standard size. 1-5/8 tubes & 2-1/2 collectors I believe
Carb ?
Dist ?


Questions are .....

The local guy who will be doing the exhaust & dialing everything in told me to use a 600-650 cfm carb of my choice. I was leaning towards the edelbrocks only to keep it matched up with the top end. What's confusing me is the Edelbrock site is showing 800 cfm carbs with the intake & carb matched sets for a 350 sbc. Also will that intake in the 2099 allow clearance for the hood to close with a drop down style air cleaner ?

Whats the difference between running a HEI alone or adding the MSD 6A to it. I know what the box does , just wondering if it's worth the added expense. This is more of a down the road question if I build up the motor more. I plan on getting a new HEI and using that alone for now as the stock one is probably a slop fest with stretched springs. Whats a good choice in this department for a new dist ?

As far as the headers can they be dropped in after the heads are in place and bolted up or do they have to go in first?

The local guy was really good but very backed up with work. He's one of the towns motor heads that works to support his race habit. He knows his stuff and people know him well also so I trust him "some what". He told me he has done quite a few "pig vettes from the 80's" as he called them and said they are a cruiser car not a 1/4 mile car. LOL, he was a bit grumpy when I was there. If he's not working for money he's twisting wrenches on his own stuff for race day. That said he's kinda short on the info & conversation end so that's why I'm here now lol. He figures in the "real world" the stuff listed above will yield about 300-340hp. In time I would like to do more to the motor as the car is just a toy and not needed as a daily driver. For now I just want to get it on the road and use it with more than the 190hp is rolled out with 30 years ago. Well that and I dont have bottomless pockets and it's been 12+ years since I was behind the wheel of something with more than 4 cylinders !!

Hi
You may want to reconsider dumping the AC, it's hot inside a vet, I know I've had a few + the one I have now.
The 6A box, I doubt you'll reap any benefit from it at this time. My vet has a 120K miles on it & still has the stock dist in it. Your going to need new springs to re-curve it anyway. I think I'd continue to use it & buy something more useful. Headers, It's easier if you put them in the engine compartment & tie them out of the way until ready to bolt them on.
Good luck
Rich
