Teksid Block with LDC cooling mod; Canton 8 QT Oil Pan; new Fluidyne radiator, Mildly ported and polished FR500 heads; FR500 Valvetrain, FR500 Intake, FR500 CB, JLT and 90mm LMAF, Mezziere Water Pump, MSD Stacker 8, Accufab Dual 60mm TB. T56 and 3.73's.
I now have 2009 miles on this motor and it is running great.
Measured Power: 408 RWHP, 366 RWTQ (408HP is at 7400 RPM). That is 470 HP flywheel.
Street Drivability: Idle is good and steady at 850 RPM with a medium lope. The lope is much more noticable than I expected, given most FR500 cam users feel the idle is fairly near stock. It is not near stock; it rocks the car. However, it is not bothersome at all. Given that I have JBA Shortys and a Catted Prochamber with a FR500 CB, I am somewhat surprised. It is not loud but have a deep "cammed" rumble.
The motor returns to idle even after being run hard with no stalls. Throttle response is like no car I have ever driven. It was outstanding due to the FR500 Intake, but the Accufab made it better. Gas mileage is about the same as stock. The smell of unburnt gas is very noticible until the cats light up (about 5 minutes) probably due to cams. No overheating issues at all.
There is a real lack of torque until 2000 RPM, so driving this car takes some getting used to. Clutch chatter (new Spec Stage 3 with aluminum flywheel), is common until you get used to revving up a little to start rolling. You can get more torque by opening the long runners from the start but the back flow against the butterfly throttle blades in the intake is bad. If you wait until 2000+ you eliminate that noise but pick up some clutch chatter. At 2000 RPM the motor begins to ramp up and you can begin to feel the pull. At 4000-6500 RPM it feels like a Centrifugal Supercharger. When you expect it to start laboring (about 6500) it does not, it just keeps pulling. I frequently lean up against the Rev Limiter (7400 RPM) without thinking I am near it yet. Tune = conservative.
Performance: Outstanding, especially 3000-7000 RPMs. Ran 12.39 @ 116.7 with a poor 60' poor hookup. Now hits 147 MPH in forth at 7400 RPM.
Pictures follow; including hand fabricated mounts for runner control next to Canton PS Tank for those interested and fabricated Alternator brackets (FR500 does not ship with these 2 brackets). I did not like the look of the runner control on the Coil covers. Sorry it rained all day yesterday and the car and engine are smeared. Also notice how short the short runners are; almost like individual TB's.
Ignore my "trick" looking beige air bag on FR500 Steering Wheel; I am going to paint of replace it with black when I get time.
