It makes too much bottom end torque................................... makes me spin my tires real hard. Went to the track to test the SBC 358 pump gas motor with the roller cam and 300-36 and while I ran an 11.38@118mph with it, most of the night all I did was spin the tires. One run was so bad I over revved the engine, (oops my bad) so I am thinking of putting either the Brodix 1016 or the 300-25 back on the car. I am willing to bet it will go 120mph with the -25. For all you Air Gap fans out there, the 300-36 is the best dual plane intake I have ever tested, hands down. Was funny as a few guys I was talking with were running real hard tonight so I asked what they had. One guy with a 2nd gen F car had a 455 Pontiac and was 1 tenth quicker and 1 mph better. Another guy with a 60's Chevelle had a super nice 406 with aluminum 195 AFR heads running almost the same as I ran. I swapped back to my bias ply tires and lost 2 tenths and 1 1/2 mph. Funny how those radials work.
