I think the company switched makers a couple times in the past 2/3 yrs so i can vouch for quality but i have read good things in the past on there use in 500+hp engines for long period of time without problems.I used a Chenoweth girdle on my 440 making 7/800hp with a factory block for over 300 passes.What hp are you making,planning to make?

Whats your HP goals? Also if going with different caps, be prepared to spend some cash on machine work as well as the cost of the caps.

Not sure on HP. Will be a 493 stroker with Eddy alum heads and a Dyers 8-71 at 5-6lbs boost.
Was considering using the girdle also.

IMO  with a  blower ,  would go block girdle  ,  if your going to ,  beat on the motor &  use the new found power  available !!

440 Source has the alum main caps with the girdle as a kit. What do you all think about their products? Or would you purchase from another vendor?

To give you an idea of what to expect i had 446"with the blower at 3%OD,2 850 carbs,iron 346 heads and went 10.41/129 all day long at 3900# car/driver and a solid cam at .559 lift.

The girdle with the main cap upgrade is an excellent choice. The only thing better would be an aftermarket block. 

My Buddy Kevin uses the BCR caps/girdle in his supercharged 446 and it makes excellent power and has held together just fine.
