I give him the number and no call for a week, so i call them and nobody answers the phone so i leave a message saying i am ready to send my heads, no call back so i try the next couple days and leave anouther message and no return. I dont think that 137mph car starts to pull till it gets to the factory limit lol. So i decided to try and find a set of Lt4's and send the to cnc since Ed's car here in town has no problem running bottom 10's at 130 with a 2,000 da, or order and wait for a set of AFR's

If that manifold is in fact available, there is no reason to stay with LT1 if your going to change it. It has a 7 degree raised runner to improve velocity, and therby allows you to make the whole combo bigger. O.K. maybe the 7 degrees ain't that big of deal but its still better. And if you have a choice, then why not?
You are listening too too much marketting BS one of their reps told a CZ28.com member they got4 whole HP out of the LT1 intake, you go right on believing it will be the best thing since sliced bread though
. They tried and failed a decade ago and are well on their way to that again. I am sure they will cast something for the LT4 just to fill the void but I would NOT bet on it being a fraction as good as you want to believe it is. FACT is with the LT1 GM stepped up in a big way and the aftermarket has struggled to provide the "usual" upgrades for it because GM left so much less room for improvement. That is why there are no readily available intakes to date and why folks are going so fast on GM casting heads. The aftermarket can still sell heads and intake though because of all the people who ASSume rather than LEARN.
