I have a low deck big block with Indy heads and have had every fender well header made for these cars as I hate fighting headers on a race car.headman made great power but tire clearance was very limited. Went to hooker fender wells and we're ok but I needed a bigger tube header, went to Mazzolini propart header and made much more power but a pain to work on. I finally ponied up the money and had some made locally. 2 1/8 to 2 1/4, expensive but easy to work on every part of the engine and transmission and can now run a 27" tire. We

Mikeysmopars, your custom headers are awesome, and I know your car runs good with them!

Yep the headers made a big difference and then struggled putting the power down but has run 9.50 @140 with 1.27 60 in real good air.

Mike! Were you at Sonoma the last couple weeks? I saw at one point that the corrected was something like -1,200 feet?

This pic was second week of February at Sanoma and the air was below sea level. I think the highest effective was was 200 feet. Normally run in Bakersfield and DA is usually 1500 to 3000 effective. I usually run 9.60s & 70s at home.

IMO. The under the body headers look nice. They are the traditional fit. What they do do is put your pipes and collectors right next to the transmission providing a wonderful heater for your transmission. It also makes it nice and tight to get the starter in. Not to mention those nicely bloody knuckles you can get. Don't forget any electric lines that can melt and for those with a push button transmission you have to protect the shift cable from melting. In regards to a transmission blow shield you basically at this time have to run a hard cover. Which can not be installed with the engine and transmission bolted in place in the car (major work). Soft blankets can melt without proper insulation (I am working on this).
Fender well headers can limit front tire size and may rub a little. Generally not enough to effect steering control. The do get all the hot pipes away from your transmission. They do give you room to work on your transmission. Electric lines, shifting cables, and transmission fluid lines are out of danger from being melted. Soft transmission blankets can now be used more easily than a hard blank since you do not have to unbolt the transmission and engine to install them. robinhoodblankets.com makes the ultimate soft blanket for fender well header cars.

RHB that sounds like a great combo for my next build.

Those custom fenderwell headers turned out great I was never a fan of the hooker fenderwell headers that I ran with my A body in the past.
