Whats up guys new to the forum, been a subscriber for years now. I have come into a situation with my '68 cutlass. See i got a buddy with a 91 240sx sr20 swapped boosting who knows how many pounds, and his been calling me out to the drag strip as of late. My cutlass is slow as hell, maybe high 16's, he should be in the mid 13's. I would like to get this car in the low 13's high 12's on a reasonable budget. These are the parts i have to get it done, 5.3 out of a 04 suburban, edelbrock carb swap mani, I got a holley street avenger 670 laying around, for the tranny i got a th400 thats been freshly rebuilt (nothing fancy). suspension is getting all rebuilt front to back, car as of right now pretty bare bones, interior all gutted. I do know its got a 12 bolt in it but have no clue to what gears are in it. My real question is what cam to use, ive read the thumper cam article a few times but i would like to retain my power brakes mainly because i just bought the whole brake system new. So what u guys think on the cam and torque converter stall, if i could get it close enough to the 12's i wouldnt care to squeeze it the last little bit. any suggestions?
allspecWhat will make the difference as to what you can do. Are you going to drive it on the street? Weight and Induction, heads, cam, intake and carburetor. It takes a lot to get a 13 sec car. Big Horse Power, and Torque.1.Weight is a killer for any drag car. Get as much weight out of your '68 as you possibly can. Find out what the weight is, and get it as close to 3,000lbs. as you can. 2.If your car has an F-41 suspension it should have a rear sway bar, LEAVE THAT IN....You could install an air shocks. If your not going to drive it on the street, then you can install drag shocks and drag front coils springs. But not for the street okay.... 3.The 400 Trans install a good TCI, B&M shift kit. A 2500 to 2800 stall convertor4.The 12 Bolt is strong for your use, depending on how tall your rear tires are as to how much rear gear you need. 3:90 to 4:10 with a posi a must5.You'll need some head work, at the least a good 3 or 4 angle valve job and some pocket work in the heads.6.A good intake and as far as a cam, what type do you want to use? Hydraulic Roller or Flat Tappet, Solid roller or Mechanical camBob
