High Performance replacement throttle body only???

[SNCTMPL]

I had them build one for me too - bored to 46mm, flow matched 61LB/HR injectors, "ultimate mods", 1/4" spacer, and an 18LB spring (running at 20PSI). I'm running it on my "383" which puts out ~430HP but, I'm only spinning it up to ~5800RPM. You can do a 50mm, from a 7.4L, with 5.7 (61LB/HR) injectors and a 20LB spring. You'll get enough flow for over 450HP up to ~6K RPM, IMO. The 7.4 injectors (17084304 74LB/Hr from 91-93) were too hard to get my 350 to idle. I needed a VRFPR with them so, I put them on the shelf and went back to the 61s. YMMV

At some point I’m going to want to have a conversation with you about some of these things.

I'll be glad to help...if I can, LOL. Send me a PM when/if you do.
