McCoy Motorsports Vortec Heads

[FLSY2730]

Look what happened this weekend, 2 new record setting ets and mph runs in awd syclones and what heads are they using , Stage 3 vortecs from Mccoy Motorsports, so I am glad to know that is what is on my truck.

Just heard alot of hearsay about the flow numbers of his stage 3 heads, I guess if the truck runs awesome at the track I would not care what they flowed.

Kinda off the topic, but what is everyone using for a throttle body, 52mm, 58mm??? Stock maybe??? Just wondering if it helps to go with a 58mm when you start running some big power levels.

100in6, what size stall are u using and what rpm have you flashed it to??

 

[Pittman]

I have a BBk 58. Cheap, good qaulity, it only takes about 10 min to mod the linkage for a sy.

diff
Yeah, throttle response.

Stock Throttle Body here.

Ditto.. No air foil either.

 

[Pittman]

not needed unless your are trying to go balls out. ie lo 10's hell there is nothing left for me to do on my truck.

I am running stage 2 heads and have been very happy with them...

Totaly stock throttle body here too.

DOnt forget that a forced induction motor plays a little different then a NA motor.

if you take the cross section of the TB against the cross section of the tube from your turbo to IC you probably have less area there...

I should be running by memorial day!!!

Nope - bone stock, but I will install my Air Foil if I can find the goofy thing! :roll:
