throttle stop cam for sbc

Way too little duration @ 50.
That puppy is a stump puller. Does it knock the tires off coming back from the stop? May not because of a loose converter.
If that 400 has any compression, at all, put something like a 274 or 276 In / 280-284 ex @ 50 in it. Elevate the Tq curve. You have at least a 5200-5500 converter in it? That cam probably makes peak Tq in the upper 4,000 RPM range and goes over when you take it up high. Take it out to 108 or 110 separation, but installed @ 106-107. That will elevate the curve and make it longer and smoooooother.
I would say gas is better. The 400's I have worked with need BIG heads to run gas and even BIGGER heads to run alky.
.02 for free.
