what kind of an idle does a street port have. im just wondering what the actual characteristics are. im not sure, but im thinking my engine has been replaced and im thinking it might possibly have a street port. it kinda sputters at idle. smooth, but a slight sputter. also, i did the pcv elim. and used an inline fuel filter to run from the crankcase to the pri. tid (i saw it on rob robinettes sight) and i was cleaning it today. there was a creamy deposit left in it. almost the same color as eggnog. very creamy. just wondering if anybody knows what it might be. thanks.

i've got a mild streetport and my idle is solid...

 

what do you gain by street porting your engine? I take it people get this done when they blow their motor and the case is split?

 

I searched google for some pictures and ran into this website-- im sure most people have seen it. It was a geocities website so i copied it over to my server. enjoy

im just wanting to know from anybody that has a streetported motor if it idles a little funny. i have just a very, very small stumble.

 

has the idle change? if so then it probably isn't the porting. Has it had the engien replaced?

I have a streetport and at 720rpm it rumbles, but at 950 it is smooth.

if it it s streetport the stumbles shoudl be consistent, not intermittent.
