We put in a 2.56 with a GM performance LT1 stock cast iron hi-rise and we r gettin 6000 at the end of the straight, before with the lower stock cast iron intake only 5500 with the 2.56..with what sounds like the same kinda rules, mexican 355 & mexican heads. We won with the 2.41 before 1 time, but your right kinda sluggish.. I think we are 86 & 86.5 RO
This is only an ASSUMPTION based on our cars RPM's and current LT1 intake vs past intakes.
TRANS LT1 STOCK
350 turbo with 2.52 x 2.56 = 645 = 6000 5500
Glide with 1.76 x 3.73 = 656 = 6100 5600
Glide with 1.82 x 3.73 = 679 = 6300 5800
350 turbo with a 2.52 x 2.73 = 687 = 6400 5900
So we are currently getting 6000 rpm at the end of the straight with the LT1 intake and 5500 with the old GM low intake with a 2.56 and 1st gear only. The 3.73 and 2.73 gear are total ASSUMPTIONS.
yeah I agree with you Dinter any of these combos could work I've ran 373 s before and if it's a track where you can really stay on it a 656 might be a little much now if you drag race the str8s and park in the corners could be a viable option but again I think Dinter is pretty much dead on with the 256
