Any help with my Stroker problem?

[RayB270]

Hey everyone,

I just joined this site to hopefully get some knowledgeable input on my current situation. My car appears to be getting too much gas as of this moment, as a simple stall results in flooded spark plugs. Anyway my current setup included a 347 stroker w/ CNC ported/polished Twisted Wedge Heads, 1.6 roller rockers, Trick Flow stage 1 cam(.499,.512), intake spacer, Track Heat intake, BBK 65 mm throttle body, 76mm C&L mass air system, MSD distributor, FMS 9mm wires, 30lb injectors, BBK 255 lph fuel pump, adjustable fuel pressure regulator, BBK full length headers, off-road mid pipe, borla exhaust, and an upgraded cooling system and oiling setup, as well as other performance related upgrades. It seems like my car is getting too much gas, and I am wondering if my fuel injectors are too big? The engine has a fairly rough idle right now and I realize it's not going to run perfect being a '95 GT w/ a stock computer. Any suggestions would be greatly appreciated.

Thanks!

Ok,,, I have a 347 stroker with similar set up. I have 30# injs as well.

What is the fuel press set at right now with out vac line attached?
What are the plugs gapped at?
where is the timing at?

That is a problem right there. The 30s are not too big, but you've increased displacement by 45ci and it can definitely throw the tune off. However, I would expect it to run lean, not rich. Most 351W swaps seem to need a chip of some sort, but if you do a little research, you can do your own tuning/chip burning for the cost(or less) of an aftermarket chip.

Where is your fuel pressure?
