Fairly familiar with the fastlane car it's mighty impressive to say the least. Definitely out of the budget unless of course

. If solid lifters require pulling the motor it's probably out of the question unless I'm confident I can do the work myself.
I recently saw another lt5 go 9200 rpm on YouTube it's a destroked motor with an individual tb setup for an intake ill post the link up. Very very cool. Got me thinking about rpms again. If the heads can't flow the air I think it's a better bet to stick with the recipe of cubes + as much rpm as reliably possible.
Does the motor need to be pulled to do the cams ? I'm thinking about some cams and intake/ih porting or would the heads need to be ported? Not sure what's the biggest choke point on a stock motor.
