Ported Heads with Comp 306

Gauging interest. Heads and cam are still on the car. I'm going with trickflows and an LE cam.

Heads flow as follows:
1.94 Intake/1.60 Exhaust .100-.600:
61/50
130/90
180/128
220/149
243/163
245/173

Assembled with comp 918 beehives, 7/16 studs and guide plates. - EDIT 3/6/20: I'm keeping the 7/16 studs.

Asking $750 for the entire setup. The heads can be ported further for additional flow.

Re: Ported Heads with Comp 306

This car made 328 to the wheels on a mustang dyno with a madtuner tune from 06 that was for a different cam. Very rich and the timing of course is off. I think that on a Mustang dyno i could have gotten closer to 350 to the wheels with a better tune.

Obviously, dynojet numbers would be between 10-15% higher.

I never got a track time because the clutch exploded last time I was at the race track.

Here is the dyno video. It was running super rich and if you watch the end of the video you'll see the white smoke - it had a leaking head gasket.

Re: Ported Heads with Comp 306

Heads and cam are now removed from the car.

Also have 30lb injectors (red tops).

Listen to the new head/cam setup with 36# injectors and a moe bailey tune

no problem bro, I love how it it sounds too. It is an LE custom grind based on my setup so I don't know if he wants me giving out specs but it is for my stock displacement. I told him I wanted a power band from 2k-6500 as opposed to the 306 which is a much longer power band (2500-6800). According to Lloyd this cam will skirt much harder at low and mid range and make more power than the 306 up to 6200 RPM.
