63mm Throttle body
Where do you send the Throttle bodys to have them done up to 63mm?
Thanks

Re: 63mm Throttle body
I saw on Marc's site about fine tuning not for the over size?

Re: 63mm Throttle body
It was bored out to 63mm. His throttle plates are matched closely to the bore negating any need for the magical GM DAG.

Re: 63mm Throttle body
Is this something needed on a stock cube, ported motor? Trying to search for answers to some of this stuff and can't find anything. Think I've read 1000's of pages on the site!

Re: 63mm Throttle body
I have had a 63mm on my motor from the time the top end was ported. Not sure it makes a ton of difference with just that level of mod.

Re: 63mm Throttle body
I did my own, had a shop bore out the TB and had throttle blades made by Kinsler....no issues

Re: 63mm Throttle body
According to Marc, even bored, stroked to 378 with head porting and top end porting, may pick up 5 hp at high rev.
