Gentlemen,
I’m starting a new thread for this.
Context !
I have a 1969 corvette with a T5 manual and a 3.36 rear. The engine in there right now is tired and unremarkable: 882 heads, non performance cam. The idle quality is good and pulling nearly 20 inches. My headlights, wiper door and brakes work well. It’s toquey at lower rpm but falls flat at 3,000. It does make driving a T5 easy loafing at lower rpm with not problems and cursing on highway at 16-1700 rpm
I just bought a 406 with 205cc aluminum heads and a custom cam. My suspicion is the cam is too big for me.
I honestly don’t know.
Part of me says: throw it in the car and see from there.
Another nagging voice is saying: install the cam that suits you while the engine is still out.
I'm on the fence.
This engine has only 100 miles on it. It’s a shame and a risk to break-in another cam.
On the other hand, will it be sufficient to run my power brakes and accessories?
Also, there’s the T5 transmission. I cruise at 1500-1800 rpm at 60-70 mph. Will that be affected? The dyno starts at 3600 rpm and I’m already under 300 TQ.
Hmmmm. If I throw the 406 in there as is with TQ under 300... will it be miserable.
Previous owner claims reasonable idle (13.4 inches at 800 rpm) and brakes work fine.
I’m worried that I spend most of my time at under 3,000
