future build questions
dreracecar:
Im here from 8 to 6 and on Sat till 5
Ran 6.90's w/ 375 sbc and a blower 1640# nothing special
you only need about 800 hp for a 1600# to run NE1 consistantly and with that, minor tuneing and adding (or taking away) weight hit you dead on the index. trying to pull 300 hp away from the engine , you lose consistancy and the motor is not happy and trying to wheel race is a 50/50 loser
Simple 454 (plus overbore if needed) 14 to 1, decent alu heads, tunnel ram injec. and a MagIII is plenty. Then I would change pistons to 10.5cr, go to Alu rods and add a 6-71 blower and you are at 7.0
As a new guy --- dont try and overthink things, other racers seem to complicate matters but if you look at the ones that run good and consistant winners are the simple ones

Not near experiance of Bruce ,but have to agree build for .1 to .2 below index and tune from there. Enigne will be happies and most predictable when its run at or near full power. One would think backing a mkotor down is easy but it came be almost as hard as trying to get extra cpl tenths.

If you are building a 632 for it you should have no problems running 7.0 as long as you use a good pair of heads . A lot of the guys here in D1 are running that sr20 head with single 4 barrel carbs and running 6.90's with cars that weigh 1900 lbs . If you are mechanical and it sounds like you are you can save some money and do your own trans . TSR racing has a great book for building your own trans . Best of luck with your build and keep us posted with your progress.

If doing your own trans you can save a ton doing some shopping.Examples I bought a coan etreme duty planetary set 1500 new,cost 600,aluminum pump new 800 cost 350 and I shopped piece from each trans dealer.Saved 20 here 30 there and to my calculations I am about 1700 to the good with some really stout parts.Agree buy the TSR book its like powerglide bible.

awesome info, that is what i would like to do, ill order up the book and i can collect parts over the next year. i/we are going to do everything we can by ourselves. done it with the vw's so wont be a prob on this i dont think. ill buy a typical chassis setup with steering, front end, rear housing, etc. and then go from there.
