Getting Close with Engine Rebuild!! (PICS)

[400 HO]

I'm in the middle of rebuilding my Pontiac 400 in my 67 GTO and I just thought I share some pics. I just finished with the bottom end, degreed the cam and set the heads. I'm now working on getting the valve train geometry set up correctly (needed longer pushrods to get the correct roller sweep.

 

Here's what I got so far:

 

67 Pontiac 400 .030 over

TRW L2440 Forged Pistons w/ molly rings

Stock rods with ARP bolts

Rotating assem. has been balanced and blue printed.

Crower 60916 Cam (222 / 230 duration) 112 LSA

.484 intake / .500 exhaust lift with 1.65 ratio.

1.65 Jim Butler Roller Rockers.

Stock 670 heads (74 cc) 9.5:1 CR with slight port work (clean up)

Comp 995 valve springs, new bronze guides, seals, locks and retainers.

Rollmaster Billet Timing Chain

Comp Chrome-molly hardened pushrods

Edlebrock Performer Intake with 750CFM Carb

Headman Headers / Pypes 2.5 dual exhaust with Super 40's Flowmasters.

 

Some other shit but you get the picture... Kauffman Racing up in Mt. Vernon has the same exact set up with one of there 400's in a Firebird and it dyno'd at 420hp / 475tq. Should be back on the road in "2 weeks" . (With help)

Them "pushrod" thingys are a pain in the ass!! I had to fork out another $100 bucks cause the stock ones were too short!! This was the roller sweep with the old PR's..

It's just a tad off center.. .. With it being like that, it would have significantly worn the valve guides. so to gain a that 1/8 of an inch.. I need longer PR's. Oh well... keep on keeping on.
