Thread: Engine wanting to run after shut off

Tweet

ok i know the engine runs around 192 to 193 that is coming from the top of the manfold, im running 350 big valve heads and headers with a 3 stage over rv cam on 89 oct. pump gas. lately it hasn't been giving me any trouble on some times not all the time it does it.
thanx cd

what are the combustion chamber size for the heads you run?

What are the cam specs?

Then I will let you know if you need 91 octain or if yur good on 87.

oh yes.

plus head gasket and piston specs.

If you please.

im running a 3 stage over rv. i can't remember the specs on it it came with the edelbrock proformer. i got the metal shim head gasket. .060 over pistons. im running the big valve 350 heads i do believe they are 194cc. i think.

I had the same problem with my 327. I retarded the timing and put smaller jets in the 600 carb I had on it. Ran like a champ after that and shut off and stayed off. Bart

Some times not all the time my 327 still wants to keep running after i turn it off. what could be cousing this to happin? the timing off? ummm or the carb. loading up and still shooting fuel down into the engine or what? So what can i do? if you need any specs on the engine i'll get them to you.

Most of the time its as simple as the timing being to far advanced.

Thanx for all your guyes help. Just to make sure that its not my timing. how can i check it with out a timing light just by the sound of the engine or what? it wants to raps up fast once i got it to where it can hit about 40 in 2nd gear in an 81 pick-up with a 4 speed. 1st is to low of a gear but i bet you all know that. but now i can get to 30 and its tacking out. so is the timing to far advenced? or what. sorry i just keep asking qustions.

ok i bet this is going to sound stupid but when you do it the engine has to be running right?
