Kevin in Seattle is a great distributor and a wealth of knowledge that he has been more then willing to share on this forum. The same goes for ttr in south africa. I did a 400F build a number of years ago and continue to do mods on it and these two guy's with there expertise on everything specific of what to run from cams to different pistons out there on ebay etc and oil pumps are the experts. Anything they offer is the best option and well worth the money, just order from them and you won't look back with regret. There's alot of stuff I wish I woulda spent that couple hundred extra from them after all the money for the build. Then there's stuff where I listened to them and bought it and glad I did or my rocket ship is.
