Warning, if you make the front suspension too stiff you're going to end up with worse traction in the rear than you would have had stock. Also I strongly recommend drag radials.
Stock Coyote will hold way more power and be way more reliable than an LT1
Again, you're stage 1, don't worry about...
What's bullshit is when you buy something online
$500 - RACE CAR PART
$30 -TAX
$25 - SHIPPING
and then they try to add another couple bucks in 'handling fees', 'express shipping', 'shipping guarantee', 'shipping insurance'....
I remember NewEgg doing that crap on computer parts. Bought...
You'd spend a ton of money on something like a Cobra jet intake, headers, comp cams stage 3....end up with something that's not as drivable etc and only make another 80hp
Steeda's car only made 450whp with headers and E30, not sure if they had slicks on it though - that would suck some power. They also had some lightweight wheels/driveshaft so it seems like it should have made more but I'm not sure what gear they were in either.
