Engine stalls when revving
Recently got back my sbf from machine shop , had it stroked to 347
Same time I changed heads, cam, tconverter Re assembled the components , engine fired immediately broke in the cam And every time I rev the engine 2500rpm + it bogs down then Stalls I've replaced wires coil and even the dizzy I chanced springs to bring timing on earlier I've changed the fuel pump, I have a regulator and gauge showing its working I'm still playing with the timing, as I'd like to get smaller bushings for my msd mech advance I have not got a vac reading on it yet, that's my next step, but I have ensured no leaks What do I look for next? I'm f*#%king baffled Here's my build so far Thanks for the help, appreciated >>>>>>>>> 23 T Bucket 2000lbs >>>>>>>>> 1968 Ford 302 >>>>>>>>> Bore .030 stroked 3.4 = 347ci >>>>>> Probe industries Forged Flat top 2618 aluminum Pistons 10.6:1 (475grams) >>>>>> Scat Crank 9000 material >>>>>> Forged Scat 4304 I beam Rods 5.4length with ARP cap screws >>>>>> Pro Street Dampener & SFI approved 157 tooth flex plate >>>>>> *4 deg cam advance >>>>>>> Comp cam # 35-246-3 >>>>>>> Duration at .50 is 230/236 >>>>>>> 110 lobe separation >>>>>>> .523/.523 lift >>>>>>> Hydraulic flat tappet >>>>>>>>> 180cc alum SBF heads 60cc >>>>>>> 2.02 intake valves >>>>>>> 1.06 exhaust valve >>>>>>> Springs Seat pressure: 132 lbs. @ 1.750 inch, Open Pressure: 293 lbs. @ 1.250 inch O.D.: 1.430 inch, I.D.: 0.697 inch Dual valve springs with damper Approximately .540 inch max lift at recommended installed height >>>> 7/16 push rods >>>> 1.6 aluminum roller rockers >>>>>>>>> x4 duel IDF Webber Carbs, MSD Pro Billet Dizzy, Mallory Coil >>>>>>>>>21* Mechanical Timing, ?
