Since you are trying to restore a matching numb. vintage Vette etc Bro!... geez. Sup with the bark?
No bark....for that matter no Corvette mentioned either....Besides, I only do big block Vettes...I'm kind of a hard core 68 roadster, big block, four speed and side pipes kind of dude...No air conditioning radio delete...
I know, I'm a sikko..

But yeah, I have to agree, if building a numbers matching deal, then you gotta go back to old school...But if looking to smear some cologne on a stinky small block and just add 30 HP, a set of Vortecs cost almost nothing and do the job...
