I have one of Robert`s aluminum 482`s . First , since you are close to him , it makes sense from a shipping standpoint .... it cost over $700 shipping from Ca. to SC , but he has the ability to get some really good shipping rates .
The engine , with a few exceptions , has been strong and trouble free . First problem was with the carb that came with it ... not built by Robert , but from the Carb Shop out there . It was a complete piece of junk from the very beginning ... running so rich , it fouled out the plugs . Sent it back and they rebuilt it and it still would`t run . Sent it back a 3rd time and was still not working when I got it . Bought a box stock Holley and it was perfect . Not Robert`s problem , but stay away from the Carb Shop !
The second issue was a leaking Aviaid
oil sump . Robert normally uses studs , but told me he ran out and used bolts instead . they were just a hair too long and bottomed out before compressing the sump gaskets completely . That one drove me crazy for some time unit I figured out what the issue was .
Other than that , it has been a great engine with about 2000 miles on it so far and one track weekend ( 200 miles ) .... soon to be two more track weekends .
Repeat ... stay away from The Carb Shop carbs .... go with QuickFuel , Pro Systems , Holley ... anything else but them .
Robert was great to work with and will help you all he can , if anything comes up .
