Hi Everyone ...I need help I have a 66 gto matching numbers original tri-power car which I am now looking to make into a G machine.

1. Suggestions for what chassis to buy ? I have looked at the schwartz performance one , but have also heard of the roadster ones, which is good, are the values worth the price ?

2. 6 spped tremec or 5 speed ? anywhere I can look for a good deal ?

3. LS3 motors ? where is the best place to get one cost wise ?

anyhelp would be grateful.
