I have a original 1970 pro stock maverick DARRELL & LARRYS MR ROLLBAR built and raced by Darrell Droke it had a 427 SOHC engine other cars had BOSS 429s or 427 tunnelports. I have lots of pictures and info on 1970 maverick pro stock cars. The cars in 1970 almost all ran dana 60 rear ends out of B body mopars no subframe connectors the tires could stick out 2 inches past quarter panel per NHRA rules my car had 8.5 inch wide wheels with 3.5 back spacing a 12 inch tire is possible with out moving leaf springs in or tubbing the car. The biggest problem building one of these cars is moving the shock towers out 30 to 32 inches and front suspension out 2 to 3 inches you need 30 to 32 inches for a 427 sohc or BOSS 429 to clear valve covers/cylinder heads .These cars changed week to week as speeds went up and racers tried new things.
Mr. Rollbar is your resident expert on these cars. He has all the early pictures, documentation and the real deal sitting in his shop. You can get a 29x12.50/15 on a 15x11" wheel on a Maverick and meet the 1970 Pro Stock rules. No mini-tub, no relocated leaf springs. Here's mine with a stock rear suspension with a custom made 9" to fit the wheel offset. SPark
MRROLLBAR can you post some pics of your car, the, the history etc, would love to know how many on this forum have old prostocks. Duane
Great thread, as I was also around to enjoy watching the first Pro Stock Maverick's. As a note of interest, Canadian Barrie Poole ran a 429 SCJ Comet PS for a while. I don't think it set the world on fire, which was a bit out of character for one of Barrie's cars. He later switched to a Cleveland powered Pinto. Too bad the Kaase P51's weren't around back then. It might have made the wedge competitive with the SOHC and the Boss of the day.
This is correct I have two pictures of Dyno Dons SOHC mavericks ! The Early one looks like a bracket racer that is jacked up with slapper bars while the later car is a real race car that is tubed lowered and had ladder bars and 14 33 tires
Photos of Pro Stock Maverick's are not hard to find: https://www.google.com/search?q=Dyn...ved=0CAYQ_AUoAQ#tbm=isch&q=Pro+Stock+Maverick
Here is a 1970 Pro Stock that ran a 351C. It was sponsored by the NW Ford dealers in the Washington/Oregon area.
The main reason they hooked so good was weight transfer! When a car plants the tires proper the power slams the rubber into the pavement causing the front to lift! When you have a 2400 pound car packing all the weight on the rear tires it will hook! Most used a 50/50 drag shock in the rear and a 90/10 shock in the front but some times the 90 /10 caused to much transfer then a 75 /25 shock was used!
