we finally got (big blue) our 71 mach 1 to the drags at bristol this past sunday. it was scorching hot!!! 88 degrees 4000 ft. da. 29.10 barometer. our previous best under good conditions at pinks oct. 2010 was a 6.51 in the 1/8
mile 107.15 mph. we ran 3 passes in the heat and had times of 6.401 6.404 and 6.404. best mph 108.30. we put new front trick springs on the car and the car transferred the weight better. we also completely rebuilt the front end. strange disc brakes all new suspension parts. but i think our biggest gain was a new pro systems carb. we had a holley 830hp that was a modified round track carb.the guy at pro systems was at pinks in october and said our car was real lazy fron 60 ft. to the 1/8 mile. i will say this it aint lazy no more. many thanks to pro systems!!!!!! i cant wait to run a couple of 1/4 passes in good air this fall. we are hoping for a low 9.90. i dont think thats too bad for a 3100 lb 71 mach with a pump gas 409 ci cleveland!!!!!!

How the heck did you get a 71 Mach to weigh that little!!? I've seen 3700+ lbs on a 351 Mach w/AC

I would recommend ProSystems Carbs to anyone. Out of the box mine was spot on. Best $702 I ever spent. The best customer service in the business. I've called Patrick, the owner, from the track and he helped me.

Can you tell us a little about your combo?

You'd run maybe 6.60~6.70 here as our baro would be more like 27.9 and you could add another 10F. A good carb is worth it's cost every time - makes a big difference. Heard good things about Pro Systems.

You wouldn't last 10 seconds in the pits here June through September LOL. 4000~6000 DA with starting line temps in the 140F+ range. If was 113F in the shade here last weekend and I cooked 8 lbs of beef ribs on the grill. Scorching hot my eye!

as I understand it it was made for classes where they wanted a bunch of airflow but rules limited them to 1&11/16 butterflys so they opened up the venturis to that amount and killed the booster signal . even when they used annulars it didn't totally fix it .

I had an 830 too it would come outta the hole but then spit a little ways down the road .when the pump shot ran out it took a while for it to pick up . I just traded it off rather than try and tune it

I go to bristol sometimes , how often do you get by there ? I might look for the big blue stang .

Nice job. I'm also sold on Pro Systems carbs. I want to try the new single butterfly on the Mustang road racer.
