We're booked for Wednesday and getting my pal Kenny's Firebird ready for the chassis dyno. We were setting the lash the other day (and replacing a few broken polylocks) and I just happened to have the camera handy....
The basic combo is:
67 Firebird convert
400 Pontiac
BME rods and pistons
7.5:1
Ported E heads, intake flows 320 @ around .700 lift
Ultradyne solid roller, 276@ .050",.630" w/1.5 's, on 112
Kuhl 6-71, 30% overdriven (that is not a typo!)
two 9375 1050 carbs
2" Hedman race headers
3&1/2" exhaust to the axle, with Scott Brown X pipe and Hooker Aero Chamber mufflers
TH400, Art Carr 10" blower converter
4.56 12 bolt
29x10.5 "W" Hoosiers
the shortblock is getting tired, it's been bored/honed and re-ringed a few times now, piston to wall is getting very loose and this block is about done. It is just a 2 barrel 400 block from a Catalina and nothing special, and I know Kenny will just laugh if it blows up, as long as he makes beaucoup HP.
We can't drive the blower any harder, but we can slow it if the 30% proves to be too much. It sure feels strong on the street though....
The burning question:
how much HP/TQ will it make,
assuming it doesn't blow up immediately?
we're going to Advanced Chassis Dyno in the Sterling Heights area this time around.
We will have a Compucar 1000HP plate kit on hand, but that is just for S&G, and not to be counted in.
Guesses, anyone?
