What headers are you running? I want to run the between the frame rail's style but don't see many options other than TTI or making them,,pic's and link's if you got them.

I have had the TTI headers - they fit - but man you need a box of band-aids and a 12 pack to install

I have heard the Pro-Parts fit - but hang low

Their was one other - but I cant recall - ProSport might know

I loved my Headman fender wells. shortish 2" tubes and long collector. I know that's not what you want but I think you should consider

Dont have them and never saw a set in real life but here is another option.

We ran McCandles (Pro Parts) for years. I really liked them but, they do have 1 tube outside the frame on one side and 2 on the other.

We make them

thats not an issue as my Hedman smallblock header's have a single tube that is on the outside on each side.

I ran fenderwell supercomps for years and finally built a set of custom fenderwell headers in 2.250

You have a PM on this

Did you test to see the power diff?

Picked up .15 in the 1/8

No way I'd have in chassis headers on a big block a body that still had torsion bars. Been real happy with hookers on a 470 with Indy heads. Easy to work on and easy to take off. However I would like to see a set of in chassis headers on a big block a body without torsion bars.

no torsion bars here, took them off a long time ago and switched to coilovers,no motormounts either have front plate, still have stock K member with Cap auto upper and lower controll arms but still have stock steering,,but thats another post.

Here's mine Bill .

which one are those?

Pro-parts don't remember if I had the hood off while we were at the track or not

Bill, in my opinion there's only one way to do it right since you don't have torsion bars or motor mounts and that is to have them custom made to fit your car. That's what I'll do next time for sure.
Another option would be to find a set of TTI 2 1/8" step headers to test fit in your car.

I've used TTI 2" underchassis headers, ProParts 2" and MadDog 2" and they were all just a huge pain with torsion bars and inner fenders.

The Hedman fenderwell headers that Sixpackgut mentioned are something that I always wanted to try as they made more power than anything else on several cars that I read about.

If you run the hedman fender well headers don't you also run into tire clearance issues where a taller tire will hit plus you can't make Sharp turns without them rubbing. I'm not sure just asking

If I remember right,,you don't have inner fender panels. The TTI's are CLOSE to just about anything. Not having inner fenders and no torsion bars would be a big +. You know my car,,all original front suspension/torsion bars/steering/inner fender wells/etc......it takes 4 hours to get the starter off and 4 hours to get it back on with the TTI's. Mine is an RB with Indy EZ-1 heads,,,your low block 'may' be better or worse. You ain't gonna' like the extra work/time involved with an A body/B/RB engine combination!! You'll enjoy the power, but the work required in routine maintenance is making me want to go back to a B body car.
