Yes,
Precision
oil pumps in Madera, CA. I think the owners name is Doug. They sell (possibly assemble) very high quality rocker arm and
oil pump asseblies. I get 90 psi out of their high volume pump.
Both Brent Mills and I got a set of roller tip rocker arms in which the adjuster caps were not properly heat treated. Doug was very quick to bend over backwards to fix the problem in both cases. Including hand delivering a package to the post office and sending me a new set priority mail so I would get them the next day. 100% no cost. Which seems only right except they sat in my toolbox 14 months before I installed them. I got a good feeling about him from what could have been a bad situation.
I will be honest with you, If you don't buy this I might. I put a 427 in my cobra because it was "original" and I got a nice period C5AE medium ride side oiler. But I have 3 times in my engine you'd have in this. This short block makes mine look enemic. slap on a set of edelbrock heads for $1200 and you have a great street motor.
Yea it's been sleeved, but so what. Every Ferrari engine built has been sleeved (aluminum blocks) done right it is a benefit. It will last longer run cooler and you can bore it out at least 3x.
I'd be happy to help with your deal if you decide to do it.
