414" 18* head SB road race motor
I ran this dry sump motor two times in the car below, it has about two hours on it and ran a 2:25.0 at Road America, one overall win and one 2nd place...it will go faster. Dyno sheet says 635hp but it pulls away from 700hp motors (it was only on the dyno long enough to make sure it ran, didn`t leak and to set the timing)
Dart little "M" block 4.125 bore /slightly lightened
Callies lightweight crankshaft 3.875 stroke
Dyers M-300 6" rods
JE pistons
C-line oil pan modified to work with Corvette headers
Calico coated bearings (rods & mains)
Brodix/Weldtech, (Hutter 921.2) CNC 18* heads w/ti intake valves and Inconel exhausts
T&D 1.6 shaft rockers
cast GM covers w/spring oilers
Edelbrock 18* Victor Jr intake/ ported
Isky roller camshaft
Isky premium roller lifters & Isky Cryoed springs
MacKay aluminum water pump modified for water lines
available w/or wo accessories and a custom made triple step set of 18* headers and side pipes for a C-2/C-3 (the headers cost me $1700).
No accessories- $10,000.00, accessories & engine price negotiable.
PM if interested...redvetracr
PS: I am selling because the current rules enforcement in vintage racing won`t allow me to run this motor without a significant weight penalty.

thanks, without a rich wife or a trust fund I`m just doin the best that I can. Before the 2005 R/A BRIC crash no one cared and I was just trying to keep up with the millionaires....then 18 cars got wrecked, they placed some blame on all the "overprepared" cheater cars (none of which have come back to race) and made my motors illegal and unapproved (the unapproved part is really what counts). Actually if you run in the back of the pack you can still run a 500" (or larger) big block an all aluminum SB or a stroker Ford or Chevy and no one cares. Interesting how now all the fastest approved "legal" cars are going faster than most of us cheaters did....I can`t figure that out but if I can sell the 18* motor I might build an all aluminum 427" big block....that one should see 740hp easily.
