id say 7.50's but i think a 28" tire would be better than the 29.5 with the 727. this is if you can get rid of .2 of the 60'. i have always run super stock springs they say cal tracs are more consistant and i would believe that to be true.

do you run 90/10 front shocks?

yes but i dont think i had the front travel i needed..i have learned that if the front dont work the back will not work either..gotta get the weight to the back..my car should have had some 1.4/1.5 ..i have a buddy that has old 30+year old springs and has been 7.10 with a 360 and 1.4x 60' not just 1 time but every time he runs the car...oh oh wait and on 3 yr old m/t et street tire that ha never takes off the car..the car just works..but every car will be diff.. also i had a 950 hp that seem to do well on the car..i tried a 750aed and bg that had been reworked by a custom carb shop and both lost time..now i didnt make any changes to the carbs (loner) but didnt help any......al so check your pinion angle...i had 6 nose down with no snubber...alot of people told me i should have tried 1 but i just didnt,,that may have been my problem..but will never know i sold the short block to member here..i'm going big block now lolololo

..... but i think a 28" tire would be better than the 29.5 with the 727.....

I don't understand this statement. I would think you would want a taller tire to make it easier to hook, more side wall to absorb the shock of launching the car. I have always used the tallest tire I could fit under the car for this reason.

Could you please elaborate, maybe I'm missing something.
Thanks

ya the tires really aint my problem i like the tires i was thinking next time i buy slicks to get 28s or 28.5 the slicks rub a little but really no big deal i had always heard taller tire better to hook?

i was just thinking that the 727 probably does not have the low gear set that you could have with the 904 (274) looks to be for 1/8th mile. the 28x10.5 mt stiff side wall will help keep the tire from cupping, last a lot longer and go straighter.
i to run the 29.5x9 mt but i have a stick with a 2.90 low and a 5.13. i am going to the 28x10.5 next year. this is just my opinion but for cars that weigh over 3000lbs i think the stiffer sidewall will be better. alot of people are having real good luck with the drag radial makes sence to me a tire with more air in it rolls easier than one thats about flat. just more money
