I awaiting delivery of my newly purchased 1976 triple black Cutlass Supreme T-Top car I won on eBay. 13,425 original miles one owner garage kept car. I want to mount the fattest TA radials I can fit on stock 15 X 7 SSIII Rims. I also need opinions on headers and dual Magna flow exhaust. I will need to sell my 69 Z-28 clone before going too crazy spending money.

 

Well, for starters you'll need a double hump trans crossmember from a 73-74 car. All 1975-up A-body cars were single exhaust only and thus have a one hump crossmember.

 

I say the Hooker Competition headers would go nice with a stock 76 350.

 

X2 with the Hooker Comps.
I purchased the Hedman Shorty headers although they fit great with no issues at all... The drivers side exhaust pipe from the header has a tight bend to keep the pipe up high anuff. I would go with the Hookers as well.
Hope this helps!!!

Hope this helps in making your decision.

I wouldn't go larger than 275-60-15s on a 15x7 wheel.

 

I agree with Kenneth, I have a pair of 245 60 15's on a set of cragars and with the basically stock 350 it was impossible to chirp them. Also to add to your muffler choices, I put the flowmaster super 44's on and it sounds good with full tail pipes.

 

Did you get those Hedman's coated? Was it aftermarket?

 

I ordered them with the coating.

 

From where? Summit doesn't show that being available in their Catalog.

My choice for muffs are dynomax.
I'm not big on flows, I have them on my '70 Supreme, they just sound to tinny.
I also have Magna flow muffs on my '68 Cutlass "S" and hate the sound, going to Dynomax as soon as I can.

I ordered them from performance improvements in Toronto, I forget the order number, but they they were shipped up here from hedman. I had to wait a few more weeks back when I ordered them because they sent them out for coating.

 

I may be interested in them if you go long tube. The larger tube size will help with my future plans.
