Hello there, this is my first post and boy is it long past due.
I have a sbc 355 in my datsun that me and my father began building about 3 years ago. He is a mechanic and has been building sbc's all his life but unfortunately he is no longer around and I've continued our mission to get this thing up and running.
But all I know about this is what I've been through with this car, and am still very new to it.
Well my issue is fuel related I'm sure of.
I can't tell if she's starved or flooding.
Idles great but as soon as I get it on the road she starts running like crap. Getting some black smoke but nothing crazy.
I've fouled out the brand new plugs I put in 2 days ago and the engine doesn't even have 10 miles on it yet. This leads me to believe I'm flooding it. My electric fuel pump reg is set at 6.5 psi.
I've tried 7 and I've tried 5.5 but still the same.
Runs great until spark plugs go out.
Sorry if some of this seems incorrect and please correct me if I'm wrong but this is what I can remember as far as engine parts go.
4 bolt main with steel crank
2.02 heads (not aluminum or w/e)
282 cam (I was told comp cam?)
Edelbrock 750 cfm
Holley performer intake
It's bored .30
Forged speed pro pistons
Holley electric fuel pump and regulator running from the cell
If I missed any important parts please let me know and I'll answer any questions I can.
Any help would be greatly appreciated
Thanks.
