I was going through some old posts and saw the one I made in 17 and thought I had updated this a while ago, guess not. OK, for all you CFI guys out there here are some upgrades I have done since this motor...in 18
The TBs flow 760cfm, flow verified on super flow SF-600 bench. Fuel system is my own version of parallel plumbing using external Aeromotive universal FPR, vacuum referenced. Running 24.5psi WOT and 18psi @ idle with 454 90# TBI injectors. The exhaust is Hedman headers with 2.5" SS true duals with X-pipe into Hooker max flow mufflers.

1. New GM SBC block - 383
2. New heads - AFR 195 Eliminators
3. New forged crank - Eagle
4. New forged pistons, Wiseco 10.5
5. New forged rods - 6" FSI I-beam
5. New cam Got rid of the Straub cam that was brand new with only one dyno pull and a 100 miles on it and installed a Bullet roller cam
6. New valve springs - LS
7. New coil and module - DUI
8. EBL Flash II ECM mod
9. Updated tune
10. Best time so far with this motor with only 840 miles on it was 12.73 @ 109mph, it still has more power in it for sure.
NOTE: Had tranny issues going into third, but I think I may have fixed that now and hope to do the 1st gear 700r mod and get the car down to 12.40-12.50 range, maybe even lower? Getting closer to Ben 73's 84 CF with his 12.20 pass. The motor is hauling *** and love the new power it makes. Hope this helps a bit more for you guys wanting to increase your CFI hp.

It is the shift plate mod so you can actually put the selector lever into 1st gear and hold it to when you want to shift into 2nd vs only being able to put the lever in 2nd which is really 1st and the trans will shift automatically into 2nd, then you can hold 2nd into 3rd. I hate the no 1st gear hold out. Why GM made it that way is beyond me. With a 3,06 1st gear in a 700r4, that would have made for a much much better launch and shift vs current.

Oh, and one more thing about my fueling. I use the 255lph in-tank pump that is very quiet, just like stock to keep everything feed. The only time I hear it is when you first hit the key for a second or two at prime. Here is the link. 255lph pmp

Oh, I thought it was actually something for the trans. I know they did it in the 4th gen fbodies also when they had highway gears in them, cant remember if it was to keep people in second gear to meet sound requirements or prevent them from trying to do interstate speeds in 1st.

Well, there is another 1st gear mod to the trans which is the planetary 2.84 conversation vs 3.06 which I have thought about doing also. If I pull the trans again, I may do that one as well.

Has anyone else done the 2.84 1st gear conversion to their 700r4 and if so, did you see an improvement in ET? Thanks...
