he thumper i got a crate motor that was from NAPA,  it has maybe 2k on it.

it is in a cruise night car, not a race car by anymeans.

its a 350 with vortec iron heads on it, i have looked and cannot see the model # on it anywhere, i have not pulled the valve covers off yet, i think the serial number is under there.

the engien dyno'd at 410 FWHP and we are looking for a little more power as it is in a HEAVY car, about 4K its an old imapla, i know it should have a big block in it ( i suggested it in the beggining).

we are at a crossroad right now its eaither a new set of aluminum heads or have the vortec heads ported, if we have it ported we would get a new cam for it as the one in there is mild its about .515 lift now.

i have heard from several people that the vortec heads are not that bad, and come alive when ported good with a good cam.

so my question is are the vortec heads worth porting? the car will NEVER see the track, so thats why were looking for cheap here, if we picked up 30-40hp we would be happy.

so what would you suggest?


thanks

and before anyone says aluminum heads  would look better if we keep the heads there going to be painted,  they r painted black now.  im starting to like this painting thing (that or im getting addicted to the fumes from the canned spray paint Smiley  ) and getting pretty good at it.    so the "aluminum looks better" is a non issue for us so please dont use that as a factor.  thanks

you could switch out the heads for eq23 heads too, theyre a cast iron head based on the vortec. they come bare so you'll have to switch over youre valvetrain components to them, but at $480 for the pair theyre still a good deal.

PHR did a buildup on a 350 with these heads using a Comp XR282HR and made 466hp with them.

here are links to the build-up and where to buy the heads

Way to bring something back from the dead. I wouldn't expect a response from Thumper, he hasn't been on here since 09'.
