Think if you were to just put a set of LT4's or afr's on a STOCK CAM"D Car.. how much of a gain do you think you'll get?? has anyone had any experiance's? I"m sure w/a decent cam grind your gain will be drastically higher than 24...

 

i know right...
and its not JUST 1K, add the price for all the other things including gaskets that you'll change etc etc...not worth it IMO

 

a) You're right, they would be a great value at $529 a pair... except that Edelbrock now lists their heads priced separately, just like GMPP. $529 each is the going rate. Almost all Edelbrock heads start at around $1,100 for the pair and up.

b) There are a ton of people/vendors you can send your stock castings to, assuming you don't need them to drive the car. In fact, you could buy a set of LT1 castings cheap off ebay and send the extra set out for porting, then sell your stock heads when you get the ported pair back. However, you're unlikely to get much porting for only $529.

 

On a completely stock engine, they are comparable to any other ported LT1 casting and aftermarket head available. 24 hp is not too bad. Also consider that you can then sell your stockers for a couple $$ and you are down to about $800. You also get the benefit of little downtime, and like stated previoulsy probably more meat to port. Also consider that these are list prices and may be able to be purchased for a few $$ less, GP's etc. I would consider them, especially once some initial flow #s, dyno #'s, and track #'s are verified.

Yep, $529/each changes everything

 

FYI--- I e-mailed Pace about a month ago about these heads and they stated I would be better off getting the LT4 heads.... Go figure.....

 

Don't you get more by just going to LT4 heads and intake?

 

Anyone have number that can compare the LT1 Edelbrock performer Heads and LT4 Heads?

 

Chevy High Performance did a test a year or so ago, and swapped on a set of LT4 heads with the stock cam. If I remember correctly, it only gained 18 horse or so. The Edelbrock hp numbers don't look bad considering a stock cam. I would question how strong they would be on a heavily modded car though.

 

If you want to do the job right your going to be tuning the car as well, and that means more money. Going half way, gets you maybe 1-3 to half as much power as going all the way, JMO.

Your going to spend maybe $1250 or so total just to get the heads on the car, that is if the above are fully assembled which I didn't notice. Shipping will probably be $40-$50, then gaskets, then all that labor and are you cam swapping too? I sure would, because you'd do half of that work all over again when you swapped.

I still would buy a budget ported set or something else first

Not bad for a mail order tune that is in the 14s for AF @ WOT.

 

I think they suck.

 

Isn't it all about port velocity and low lift flow numbers?

 

Are the LT1 heads cast iron or aluminum. If there cast iron and the edelbrock heads really do give you 24 more horsepower over stock lt1 heads then i think it would be a great deal. First aluminum is much lighter and lesser weight means faster car. Secondly aluminum can resist detonation alot better, so you might would be able to user lower octane fuel. Aluminum is also easier to repair than cast iron if cracked. This is only assuming if the lt1 and lt4 heads are cast iron, if there already aluminum then the edelbrocks probably wouldn't be to good of a deal.

 

Lt1 heads are aluminum. They edelbrock heads indeed do suck. If you want a good head at a good price try AFRs or send your heads to this guy....

He can make heads move some air.

He does excellent work and is very trustworthy.

(Not just another shameless plug)

 

Hmmm
The shop that ported my heads say that the gaind 30 fwhp when they ported a pair of lt1 heads with stock valves on a stock engine, and that was not max ported, they said that there was no mening to put more job on stock castings.
