Help to get off the line please!
First post here, please bare with me !
So I built one of the 7 engines in the article "7 Hot Engine Combos - Mild to Wild" from Chevy High Performance magazine August 2003, I think it was the Muzak Mouse but I do not recall, specs of my build are as follows:
-350 SBC, 4 bolt mains, 9:1 compression
-Cam is an SSI from PAW: 214/224 duration (280/290 adv) with .443/.465 lift @50
-GM Cast Iron Vortec Heads
-Edelbrock Performer RPM Air Gap Intake
-GM Ram's Horns manifolds, 2-1/2" (clearance issue or I would have gone with headers)
-600 CFM Carb (mine is a Carter AFB)
Engine runs GREAT! It is in my '59 Chevy 1/2 Ton pickup with a Turbo350 trans and a 10 bolt corporate wtih 3.42 gears. I believe my torque converter stall is around 2100-2400 but the trans was a freebie so I didn't ask too many questions at the time!
Part throttle and WOT performance are awesome but transitioning from idle to the primary circuit is an issue. I have called and worked with Edelbrock Tech Support but alas, no avail.
Engine has 18 in of vacuum idling in park between 800-850 RPM and drops to 600-650 RPM in gear, not too much lope either; it takes off smooth with minimal throttle. Distributor is stock HEI with 20 degree weights and stock springs, for now, vacuum hose disconnected, for now (possibly forever), I am all in with 36 degrees of advance around 2800 RPM (16 degrees initial timing).
PROBLEM is, truck cannot get off the line... It bogs or stalls if you floor it.
I would appreciate any insight or advice from the experts out there or anyone that has a similar build; I know this combo will work, I just have not coaxed the genie out of the bottle yet. Thanks in advance
I got the Skyjacker hydro shocks on and they are as soft as I'm going to get. It still rides kind of firm but better. One of the main issues is the front is about a 1/4 off it's bump stop, the lack...
