As you all may know or not know my 401 is damn near ready for the dyno. I've scheduled two weeks of dyno time on the weeks of Nov 6 and November 13 of 2006 (about a month away). I have my best guess of what this 4 year project will make for the final numbers, but I was interested on what you guys think this thing will make.
Pertinent info
1976 401 AMC out of a waggy.
Bored .020 over
Decked .010
Block deburred, align bored on Bridgeport
Drilled main bearing oiling holes.
Main bearing stud girdle, 2 bolt mains with arp studs.
Oil valley oil line, (should be good for at least 50 HP right there)
Custom designed Je Pistons 7.75-1 compression, speed pro rings.
Carillo rods, bushed for a .990 pin, oil hole, full float pins with spirol locks.
Crankshaft cross drilled, standard size.
Clevite bearings.
Isky 5300 blower cam, hydraulic lifters.
Rollmaster timing set. Set 4 degrees retarded.
Around .540 lift.
Heads have 2.080 intake, 1.780 valves, 5 angle valve job,valves unshrouded to gasket, ports equally ported to same size using the Bridgeport. Chambers cleaned and re machined using the Bridgeport,polished, 64.4 CC on every chamber. Studs, 7000 RPM springs, 1.6 ratio rockers. Core wires removed. Bronze valve guides with .343 valve stems. Exhaust ports all machine ported.
Intake custom made single plane blower manifold, port matched to heads using the bridgeport.
6-71 GMC blower, toleranced to .005" clearance 3% underdriven, (about 8-10 PSI boost.
Dyers blower drive custom designed by me.
16 100 Lb fuel injectors at the intake to the blower, Fast ECM, BDS Bugcather. Vertex Magneto gutted acting as only as a dizzy with a phasable rotor..but with pressure lubed shaft and bearings.
MSD 6AL Cap box driving a MSD Blaster coil, Crane fireball flying magnet crank pickup. (crank sensor)
Aeromotive 1000 gal per hour fuel pump. -12 (3/4 inch fuel feed line split into two -8 (1/2 inch fuel feed to manifold) -8 return to tank.
Custom by me, 1 7/8 headers. Kit by Headers by ED( I would have rather had 2 inch headers but 2 inch tube is too hard to Siamese on the inside ports.
Stand alone 400 HP shot of Nitrous.
Full accessory drive, Alternator, PS, A/C
Head studs.
Custom by me 12 quart dual pick up Milodon sump.
An lastly ( I'm sure I forget a few other things[old age])
Bulltear timing cover and gears, 534 bypass adapter, -12 (3/4 inch) oil feed lines, duel oil filters.
Crank and all rotating parts balanced like the Nascar guys do, I have been sworn to secrecy on the balancing. ( Seriously) You ever see a used Nascar crank on Ebay? They are destroyed not sold. This balace job would have cost 10 k for anyone else. (Hint bananced in 2 planes)
Mondello steel flywheel, that expensive Aussy vibration dampner.
Alright now post your best guesses,
About the Dyno and the tuner, 20 yrs as Team Jaguar Head mechanic,builds only high end foreign engines, Mercedes, Ferrari, Porsche. Super something Dyno, his right hand man is a young tuner genious kid, complete with earing and funny way he wears his hat.
Kiwi Engineering is the company name located in Old Saybrook Connecticut.
I had to pull alot of favors to get this guy to do the tuning, ( he hates Nitrous) and has a 3 yr backlog. plus he's English.
Oh yea all this on pump gas, race fuel on weekends.
Ok ask questions, flame, or just sit back in wonder.
Jeff
