Builders;
Builder ‘Eddie Easy’ is going to work with Roy of Roy’sgarage.com. Roy has his own 5th bearing design, and it is now flying on about a dozen aircraft. The bearing design requires builders to send their case and crank to Roy so that he can line bore his bearing to the case and he has to process the crank to install his 5th bearing journal on it.
Builders selecting Roy’s bearing design almost always have Roy assemble their bottom end for them. Also, Roy’s bearing design requires a special safety shaft and custom-made hybrid studs. (Dans 5th bearing uses parts straight from our catalog) For these reasons, an exact head to head price comparison isn’t possible, but we can come up with a reasonable comparison for builders. Since Roy’s set up utilizes a Moldex processed 8409 GM crank, It isn’t a fair match to compare it to ‘Davie Dog’s’ engine with a Billet crank. It is a better comparison with ‘Chas. Charlie’s’ short block. After we go through the numbers I will do some notes and comparisons at the end.
( CC stands for Clarks Corvair parts, SR stands for Summit Racing, ELS stands for Ebay Larry’s Corvair parts, and ECA stands for Ebay California Corvair parts.)
