(just dreaming about the potential engine build if price was only a minimal concern)
the idea here is to build a pump gas friendly BBC that would very easily exceed 750hp/800 ft lbs that you could drive on the street using high test gas
my goal would be very high dependability and massive torque, in the 3500rpm-6000 rpm range, hp would be no real issue as I have no intention to race the car
Id have a 4l80E trans modified fo full manual shift control and a 3000 rpm stall converter and a dana 60 rear differential with 354:1 rear gears

ID build something rather similar to this 598 BBC short block

a mild hydraulic roller cam similar to this (remember its for street performance not racing)

a set of 8 66lb fuel injectors

intake similar to this

throttle body

Id want coil on plug per cylinder ignition with an adjustable height collar distributor type control

I was thinking closer to $16K if its done to my standards... but hey its not that bad if you consider it as a project spread over several years

Hmm, that’s grumpy ?, I don’t see a lsa number. Intake lobe center is 108, that tells me too much overlap for forced induction motor!

Would that cam work with a blown motor?
I am thinking you need one with 112-114 lsa so the overlap is shorter. Longer the exhaust valve is open at overlap the more boost is pushed out the exhaust! Oh yeah, if I am right the exhaust duration should be a little longer too. Seen a couple blown engines and they all seem to have about 10 degrees more exhaust duration.

yes thats all valid useful info

yeah, that $4-$5k added for the trans cost,
is most likely all too true.

but by todays prices,
having an exceptional car you proud to own that costs you under about $25K is not all that bad a deal
certainly better in my mind than spending $70-$80K on some of the newer options
besides I like the look of the older c4 corvettes

Yea, can't argue with that statement ! I'm not going to spend ($70-$80K) that kind of money on a car.

If I win it Grumpy.... They say I can give away $15,000 tax free to someone... So if my math is correct, I could cover the site costs for you for the
next 75 years. Or.... just give you the cash to jump start your dream engine.

Yeah I was gonna say 15-16 k for engine and with 4-5k for transmission, then another 4-5 k for suspension and little knit pickin stuff, between 25-30k would build a real street performer!
