Gt/ba ???

FED 387 · 08-15-2021, 08:24 PM

A local racer wants to convert his 68 Malibu Coupe into a GT/BA using a 454/450 engine ---his car he says weighs 3400 pounds ---what type of power is he going to need to run the index of 9.80 and to run under the index 4-5 tenths??? Is this a "costly" mission or can this be "easily" (LOL) achieved??? Thanx FED 387

Well how many other 68 Malibu’s you see in GT/BA? Or factory rear wheel drive cars? Costly and foolish.

Wild guess 760 tough to be fast with that combo.

I think that would be a cool combo. Something different.

Online calculator says 715 to run the index and 800 to run 40 under.

thats what i thought i read---now you multiply that by 7 or 8 . whatever that number is something and add 175 pounds driver weight to get your car minimum weight correct?

6.5 plus 170 driver.

GT/B and GT/BA - 6.50 Lb/HP 3023 -261 3193 9.70 9.80 6.32 6.38

With a 1970 402 375 HP it makes the weight of the car better..

GT/E and GT/EA - 8.00 Lb/HP 3240 -43 3410 10.00 10.10 6.50 6.57
