Looks good, Greg.

Question : Why the longer exhaust distance from the head to the chargers? Seems like a lot of surface area to deplete thermal energy that could be used to spin the chargers. Or is this irrelevant for the turbo in the bottle?

Edit: Those long tubes do look neat though. :D

Working with pulse, using the merge collectors. I would have liked it to be closer, but we did the headers that way to possibly run a Pro Charger at some time in the future.
Car weighs 1745 with me in it. Still need to add the weight of one nitrous bottle.
 
Good Luck. I hope you dont fight convertor issues, are you trying a coan 10.5" first. Just in case, I,ve been dealing with Dennis Reid and he has his chevy bell now machined to accept a 12.5" just cant quite get a 13" to fit. Your lock up and efficency may not be as much issue as mine was with increased rpm. But Coan couldnt get it done back then for me either..... in a 10.5" cover that is. Hope it works out good for ya though.

I have a lot of experance with the small converter and anything tighter will shake the tires . I plan on stalling about 4700 to 5000, I don't plan on a lock up.

Charlie Stewart Race Cars built me a chassis similar to what I would run in A/ Dragster Automatic. Which is a 1500 hp 1700 lbs car that runs 6.40’s. It’s a 255 inch slip joint car, with all of the weight savings options. I have 2 sets of tires to run 33.5 X 16 for bad tracks and 33 X 15’s for good tracks.

Charlie builds about 15 cars a year mostly Corvette roadsters that with the same running gear as my dragster would weight about 2100 lbs. with driver.

I would love to see a chevy Dmax in a Chevy 63 Corvette
