Re: maximan revs
In 1950 I twisted a stock 221 with 3.78 gears and 6.00 x 16 shells to 68 mph in 2nd. Really hummed. I could always count on 86 to 88 mph top end and once hit 92 mph. I had another 38 221 that would do 89 mph. Never blew either engine. Had a lot of fun dusting off the Chevies.

Re: maximan revs
I have another 38 ford that I restored with a 221, 3.54 gears, 6.00 x 16 tires and the speedometer is accurate with a GPS. At 50 mph in second, a Snap-On tach shows 5,000 rpm at 50 mph.

Re: maximan revs
'35 Roadster 3.54 rearend - single 97carb LB 221" will do 90+mph ... so around 3800rpm? Run out of breathing it seems around there but not lacking in power....

Re: maximan revs
As well as running out of air, it's possible to run out of spark.
Wonder if Bubba has any knowledge of what rpm the stock helmet or crab and coil setup starts to crap out?

Re: maximan revs
My Helmet distributor with 11A advance parts was run on my friends' distributor machine
to 3000 rpm (6000) engine. No spark scatter or misfires (has Pertronix module). |
