At 4k Rpms, the Engine backfires abit, not to bad, but bad enough to be harmful to the engine, I'm thinking that its the exhaust system, or maybe just the engine itself (real high mile engine) I got the timing done and what not, so I'm pretty boggled about what the problem is at this point.

And afew more fast questions:
How much does a 13b motor rebuilt sell for?
(private sell, such as from this board, company engines cost WAY to much.... Side note, you can buy a 454 Chevy for the same price as a 13b from some companies )

What is a good exhaust system for this car, is it possible to make a custom exhaust (I mean, is it possible to make a better exhaust system then the ones I could buy, or would that just be a waste of time?)

Thanks all

I'm not sure but could his problem be the anti after burn?

 

I dont have really, any exhaust system left. After I cut the belt on my Airpump, the car will backfire whenever you let off the gas.

If I rev it up, to say 7500, and just let it coast down on it's own......it will shoot flames, like every 2 seconds.......POP........POP.........POP....

I like it....but I'm sure the cops won't.

D'oh.

 

yeah mine does the same thing. coasting from around 6000-7500 rpm it backfires a will shoot a nice flam about 1.5 foot out the exhaust. great at night time out in some windy rounds surrounded by cliffs
