418 in 340 out

for fuel im running a home brew , i did some research, google home brew octane booster, so 4 gals 93 octane 1 gal e-85, 1 gal of xylene 114 octane avereage it out it comes to 98.5 octane , cut to 3 gals of 93 it raises it about a point. i get xylene at work for 9.00,4 gals of 93 is 11.20, 1 gal of e-85 is 2.35 for a total of 20.55divided by6= about 3.50 a gal ,ITS BEEN ALONG DAY DOUBLE CHECK MY MATH lol ... the rear is narrowed 2 or 3 in per side, 12 wide centerlines, tires are e.t streets 28tall x13.50.i had a t-ram before on a sm block ford in a light car 20 years ago and it ran 11.42 . sm. block chrysler heads in my opion flow just ok, for a hot street car , mine flow 277 @ 600, well put a single plane on and it will cut down that total air flow,( in my opion), i have heard of guys switching from a victor 340 to a super victor and gain 10 hp, but spending a total of 600.00 for a intake and some porting.this again is my veiw of intake comparissons. take the carbs off my t-ram and look down it and you will see no air obstacles to get air into the motor, if you look real good you can see the intake valve, i gasket matched the tunnel ram after i got the heads back from being proffessionally ported,plus the t-ram has some additional work done to it also. the carbs are 660 t-ram carbs, they need to be tuned, we drilled out the air bleeds and installed screw-in bleeds so it will be easier to tune on the dyno, my opion again build the same motor 1 with t-ram , 1 with 1 carb. single plane - the t-ram should make 40-50 more hp. car craft or hot rod tested a t-ram on a w-2 headed 340 with 2- 750 carbs vs. a 360-1 intake, t-ram won, and then put the t-ram on a bigger cube motor wich needs more air any way it will like it.
