What exactly is done to the heads?

If they are simply ported stock castings, then you will have a hard time getting to 500. Not saying it can't be done, but the higher dyno'd 346/7 cube motors are running aftermarket heads.

They arent stock castings, Louis at lg motorsports milled on the heads ill have to ask him what cc the head is i believe 60 or maybe 65cc's i might be mistaken tho. If it makes way more than 500 id be very pleased!!

Well, there's no way you're going to make 'way more' than 500 without larger cubes or forced induction.

Realistically, I'd shoot for 470-490 if everything is optimized to the n'th degree.

When I say stock castings, I mean that they are a GM cast head, with port work. After market castings have a leg up on GM's castings as they took what GM did, and made them better. Examples of an aftermarket casting is AFR, Perfromance Induction, MAST, etc etc.

I'll say 460/405 on a dynojet.. I would much rather exceed my own expectations with a low guess than be disappointed with not even coming close to a goal only a small handful of people have accomplished..

I went to the dyno with my current setup hoping for 430/410.. suffice it to say, I was ecstatic. My track times back up the dyno #'s as well. That's what its all about.

Why not with 30lb injectors? it would just be nice to see very close to 500 id be very happy but i know its going to very hard to do but we will find out soon enough. yeah very true djfury 05. theres a big difference between dyno queens and ones that can actually back it up.



example 03 cobra in my town with kenne bell made 704rwhp, raced my buddy with a 98 camaro with 402 that made 500hp my friend with the 402 beat the cobra. its not all about the #'s ive come to find out but its always nice

Honestly, give up on that 500 rwhp goal or else you'll be extremely dissapointed when you put down 450-460 rwhp. To get that 'magical' number takes a long time of testing different combinations of cams, exhaust, intake combinations to find the right balance. For example, you say your FAST is ported, but by who? Some people do more harm than good when porting them.

Louis gigliotti is the one porting it. His dad owns LG Motorsports. hes pretty well known and alot of people send their intakes to him to get them ported just like tony mamo they are pretty well known

I know exactly who LG is. Just don't get hooked on a dyno number because they can be skewed easily to show just about any number you want.

You need to specify if you are talking rwhp or bhp. Big difference

500 to the wheel is a LONG shot.... like others have said.... its very tough.

Look for 450 to 460 to the wheel. I would say the 47x 48x's are where most N/A max effort 347 end up. FEW hit the 500 mark. Big cams make big numbers, but loose some powerband on the street.

Also....

There is alot to be said as to the way the car is dynoed. Don't be put off by dyno numbers of people on lightest tiniest wheels they can find with there ascessory belts taken off vs someone that dynos it the way it will hit the street.

Weather and correction has alot to do with it also. Dynos can be tinkered with like The
Alchemist said to show alot higher numbers than whats true.

I did the whole 500rwhp thing and made 466..... you can see my mod list on the link in my sig to give you an idea.


***Edit*** I would also goto Fuel Injector Connections website and use there calculator to see if you will be running out of injector. I know i was right on the ragged edge of what 36lber would handle when i did my build per. Ron and Mike at Vengeance and went with larger ones.
