383 stroker
I have a 383 stroker in a 68 camaro that when accelerate from 1000-2500 rpms with or without a load on it will back fire throught the carb does not make any difference what kind of carb does the same with a holley or edlebrock 26 total timing
|
Is this street-street/strip - or strip only car ?
At what point of acceleration does this happen ? If it's just as you stab it, it could be not enough accel pump volume, even on 2 different carbs, it could be weak or not enough. Also could be your advance is not working or is gummed up within the distributor. |
26* is not enough timming even for a stock engine, should be 32*/36* total timing.

JMO Zip. I'm pretty sure my lawn mower has more timing than that! Double check your firing order too. |
Needs more timing

when I put more 32-36 in it it diesels when i try shut it off and i still get a back fire through carb, also when i remove vacum advance hose the motor dies,
|
check for vacume leaks
|
Are you sure that you have the correct vacuum source connected to the vac/adv? It may be that you have too much constant/high vacuum to the vac/adv & it is advancing too soon... while not enough timing on motor which maybe is why it dies when you disconnect the vac/adv hose... not sure, just a guess.

Sounds like your timing marks are not accurate
