what rocker arms ya goin with????

 

[Trainman]

Thanks Greg! That is just incredible , 405 cfm....Wow. We will be going with 1.7 T&D rockers per Greg Good recommendation.

 

[SrtBrad]

405 cfm? WTF!!! That is an insane flow number. Anybody got those numbers before on a NA street build with a gen4?

 

[caveman]

The intake ports peak at 405 cfm @ .700" lift. (They're 400 *even* @.650"). The exhaust ports flow 270 @ .700" lift. 28 inches of water.

Glad to have you posting here, Greg.

 

[ZCx]

are ya goin with any thermo coatin on the combustion chambers/ top of the piston???

 

[SRT10VENOMOUS]

So what did you end up running in the heads for valves and such

 

[fastestbrickonearth]

405 CFM is pimp congrats homie

 

[ZCx]

So what did you end up running in the heads for valves and such

at least 1 intake & 1 exhaust per cylinder????

is that correct????:dontknow::sheep:

 

[Trainman]

So what did you end up running in the heads for valves and such

I don't know the exact brand or weight valves, but I'm sure the intake is 2.19" and I believe the exhaust is 1.60". The solid roller cam will be .700" lift, still deciding on duration and overlap.

 

[SRT10VENOMOUS]

Wow they stuffed a big old valve in there, it's gonna be a beast if it all comes together.

Did u go with the jessel solid lifters ?

 

[SrtBrad]

What's your weight reduction goal that accompanies your power gain?

Update time! Just spoke with Greg Good and I have the preliminary flow numbers on the Gen IV heads. I think my Gen III stock heads flow between 268-280 cfm @ .600 on the intake side. Here are the numbers for the Gen IV ported heads:

LIFT.......INTAKE.......EXHAUST FLOW
.200........165...........115
.300........254...........178
.400........309...........220
.500........348...........244
.600........369...........258
.700........375...........259
.750........377...........260

Greg is calling Justin @ JMB today with the specs for the custom intake, he wants total runner length(runner and port) of 15", round runner shape, 25% taper on the runners, and have the runners extend up into the plenum chamber. More details to follow.

The cam specs we are considering are 248-256 with .700 lift, 114 LSA, Solid roller.

The valve sizes on the new heads are: 2.170 intake and 1.600 exhaust.

Update time. Just spoke with Greg Good and here are the actual final flow numbers on my Gen IV heads. Final valve sizes are 2.19 intake, 1.60 exhaust.

Lift..............Intake............Exhaust
.100------------72---------------51
.200-----------174--------------108
.300-----------252--------------168
.400-----------315--------------212
.500-----------355--------------244
.600-----------382--------------266
.650-----------400--------------269
.700-----------405--------------272

Simply incredible, Thanks Greg!:rock:

What's your weight reduction goal that accompanies your power gain?

No further weight reduction planned at this time, so I'm at 4170 race weight without me in it. If needed, I may have to redo the rear suspension and go to a ladder bar, and coil overs with a fab 9 rear, aluminum carrier and smaller brakes, which could save another 100 lbs or so.

 

[JMB Justin]

One down, one to go....

 

[Trainman]

Looks great Justin, Thanks again! Hey guys, these will be RED powdercoated!

 

[hawk02]

Need to start taking orders on these if enough want them..........Cant wait to see them coated.

 

[JMB Justin]

Thanks, and Greg those flow #'s are AWESOME, I cant wait to see how awesome this build will turn out.

Spoke with Greg Good last week, I believe he will be at the Texas Mile the weekend of March 21st. I'm hoping my heads and intake will be done by the weekend of April 5-6. I'm planning on flying into Houston on Friday April 4th, renting a car, meeting with Greg Good in person just to shake his hand, and then driving the heads and intake home safely. Any of you fellow members in Texas that would like to meet up at Gregs are certainly welcome. I will keep everyone posted, but for now that's the plan.

 

[SrtBrad]

I'm sure Robert (Mopar Connection) will make it out if at all possible. Maybe Venomous1 will finally meet the legend? Sure there will be a welcoming crew to meet up with you Jerry.
