im putting the hsr on right now, and i wanted to know if anyone had suggestions on where i should set the timing and fuel pressure? i have a 350 bored over .030, comp cams 503 cam with 1.6 rr's, ported l98 heads, around 10:5 to 1 cr, and 24# svo's. with the tpi setup, i had the fp set at 44-45 psi on my tpi setup because it seemed to run pretty good with 45 psi. i heard that the hsr likes a lot of timing and a lot of fp, so i just wanted to find out if anyone had some advice to give me for my application. thanks guys

just start at the same point. but just to give you an idea on my 360 i had with the ZZ4 cam and L98 heads, i used 45 psi and timing was 36* by 2500 rpm. now on the 383, i used 55 psi and 36* by 2500 rpm. on both, i had the 24# accel injectors.

I used stock fuel pressure and 6 deg timing.

Yes I did. Timing was set at 6 deg and the pressure was about 45-57. It made about 410 HP at the wheels. I don't know what the ECM was supposed to advance it to but that was what I set it at. It was dyno tuned at HiTechMotorsport in Ramsey, MN.
