just bought a HSR with rails and throttlebody..looks brand new...300bucks. was going to run a modified tpi intake but got a killer deal(least I thought) for my setup.. ZERO miles... 355sbc 10:1 compression, lightly ported 113vette heads(brand new) with upgraded springs...1.5 roller rockers(will prolly upgrade to 1.6s later when its broke in) XE268H-10 comp cam...intake .477 exh .480....duration
@.050 in 224 exh 231 110deg separtion. 106 centerline....cams been degreed..have BBK 52mm throttle body. debating on injector size..26's 28's 30's.. 3.73gears..auto700r4 What are realistic numbers to expect out of this efi setup?...I have 1 5/8 primaried 3/4 headers with 3 inch collectors..2.5 duals xpiped with original 40series..(very well bent exhaust)

 

30lbs. injectors. since it will need tuned

 

yeah i was leaning toward 30lbs...but my pops..keeps telling me "you dont' need'em that big".. whatever..I prefer to over build then be on the edge of just right/not enough

 

when I built my 383. I went with 24's. that was a mistake.
