I have a great et of 088 heads. ported and new Crower springs. Iconel valves 1.94 and 2.25 valves. I built them for a 700+ HP blower motor and then went aluminum. A perfect bolt on $1000.
$1,000.00

As you know - been thru this real recently.

The IE heads are real good. But supposed to be better ane the Edelbrock heads. PLUS they are like 70lbs lighter and build good HP. I have talked to lots of folks that have them and no issues thus far.

Have you pulled the motor out and/or torn it down yet?

Does this all apply to the dart alum heads?

Chris Sunkin 08-24-2008 09:44 AM

About the best thing you can say for the Edelbrocks is that they're lighter. Nice price too.

Hand porting a cylinder head is not the most economical way to make power. It's on par with and sometimes more expensive than CNC. And the result is only as good as the person doing the work. There's much more to it than making the holes bigger.

But done right, the results can be impressive.

While you guys are talking heads what do you think about Pro Toplines? I just had to replace one of mine due to a few cracks.:(

They were a great head a few years ago. Head technology moves fairly fast Plus, they were bought out by RHS a while back.

Wow! what kind of motor work (maintenance) did you do to get 950 hrs out of them?

Amsoil every 20 hrs and valve springs every 200.:drink:

He will get you the correct profile that will work the best for your application and what you want to do with the boat. 585-654-8583

Yes they are tired we lost 7 mph over the winter.:mad: And yes Bob is on my list of people to call. :cool:

We are looking at a lot of parts Edelbrock, Dart (Alum. Iron ) World ( Merlin II ) and AFR's . So many parts so many inputs. We just want to make the right choices ,I DO NOT want to do this twice. We run mostly in salt water so will aluminium hold up for another 12 years as the past heads have ?

Thanks again for all the help. :ernaehrung004:

Joby



To many parts to little MONEY!!!

Not yet , But when it came apart it did not sound good. The temp went to 165 and oil pressure went to 10 before we shut it down. We were running @ 4500 when the temp started to go up.:eek: I should have been watching the gages a little closer. :mad:
