I am in the throws of restoring a 62 samba and have aspirations to race it down the 1/4 stretch at Santa Pod. the bus wont be restored for at least another 8 months yet which gives me time to start thinking about a performance engine and ancillaries. Problem is I have no clue where to start or what I am looking for? I have no idea about which places selling performance blocks are good or whether they offer sub standard machined parts. Essentially I am looking for recommendations about providers of a high performance engines and tuning specialists that might be able to make my bus MEAN!

Any help or pointers would be gratefully received.
Thanks
