So going to that big quench, you didnt have to change the tune?
No change in jetting or anything.
I currently have the .051" piston to head distance on my 57 chevy and it pulls my 20 foot Pontoon very well.
I have pulled it with 3.00 gears and 3.70 gears I do pull 3 degrees timing with the 3.00 gears.
Normally run 38 total but 35 total is only 3 HP less at the wheels so very good power still.
I did that little piston to head experiment on my own personal vehicle over 25 years ago.
So much talk about perfect quench distance I had to find out for myself if there was any difference.
You would be surprised how many experiments I have performed just to put hear say to rest.
There are a lot of smart folks on this forum and I am sure they have also experimented.
Those years back i was driving 70,000 miles a year and the wife was also.
She put 67,000 miles on one car in 11 months and I quit counting.
I had multiple vehicles and that 70,000 miles was logged on the ones we drove the most .
Her Escort and my 78 Nova.
I also had an 82 Mustang and 78 Skylark an 1980 Pinto, 1981 280Z and 1985 V65 Magna and her bike also which is a 1987 Honda Magna.
Get tired of driving one car then hop in another one.
I thinned the herd when I moved.
I experimented / tweaked on all of them.
The little Pinto would put 305 chevy trucks to shame. Even when pulling trailers.
Head gaskets are inexpensive.
Oil changes on 2 cars every 2 weeks gets a bit crazy.
The V65 Magna got oil changed sometimes after 2 days. Hard racing ya know.
