H beam eagle rods stock 428 length
Rockers 1.65 Butler performance roller Tip
Lifters Morrell Hydraulic rollers 
Compression 10-5-1 ?

4 Bolt Billet KRE Mains and end caps Line Honed Block pre drilled

HEADS KRE 310 Ported heads Ferrara 5000 versions large HR springs
KRE FLOW NUMBERS

INTAKE SIDE            EXHAUST SIDE
 .100 88                                    .100 53
 .200 165                                  .200 116
.300 216                                   .300 156

.700 312                                   .700 218

CAM KRE HR 242 CAM

Adv. duration 296/307
.050 duration 242/248
Lobe sep. 112
.544/.546 lift w/1.5 rocker  I went with 1.65 rockers 598 lift/600 lift to maximize ported head flow usage

Intake and Fuel delivery

Port Matched TQ 2 intake and Edelbrock Pro flow port injection. Kit comes with 35lb injectors unlike  chevy guys Pontiac guys have to pay extra for the 45lb injectors I did this as they support the upper power levels

Distributer is what comes in the proflow kit

Exhaust Doug's headers 2.5 inch exhaust "quiet" flow master FX mufflers however I have the valve operated Header DUMP exhaust bypass so right out the headers it goes.. 

Timing chain and all other accessory's are stock






Transmission TKX

Rear 72 Buick upgraded Moser 30 spline axels Eaton Detroit Locker worm gear unit with 3:73 Ratio
ARP bolts rear cover with main bearing CAP supports rear disk conversion, Strange pinion yoke with Ubolt upgrade 3150 U joints/  Had to get a frame brace kit for the 1967 GTO as the frame on A body's is a little flexi weak...




What power levels do you think I can reach...?

Looking forward to hearing from cliff as he was the inspiration of this build having the only hard data 428 build on the internet with respect to power and aftermarket heads, I put my own spice on mine they are close not exact... don't want to wear another man's boots after all..


Thoughts critics are WELCOME

I'll say 580 @ 6500.

I was worried about the cam being over sized my specs are similar to cliffs and he went with a lower @ but much more lift ... I have made an adjustment for that once I had concrete flow numbers to adjust for..

It should be fine especially with a manual trans set-up.  More compression with that much cam would work better as bigger cams bleed of more cylinder pressure and with 296 degrees duration at the last point and 242 @ .050" you could have went to 11 or so and still be fine on pump gas....IMHO....

580Hp at 6200

Thank you ! We are still in the build until end of January! So still time to make changes .

Changed rockers from 1.5 to 1.65 so new lift will be .600


The issue is, the pistons I'm using are .40 10CC  Keith black 428 pistons from KRE .
You think I could get a bit more squeezed with zero decking the block ?
