im the 2nd owner of an atomic built motor , but even though I never paid a cent to brad, he was mega helpful with any questions I had , as the motor had been idle for some time ! I would get another motor off him anytime! he deals in alot of these motors and knows them inside and out! anyone read Street machine latly , there is a story of a known tuning shop banging a high dollar motor more than once due to an incorrect oil cooler setup. we play we pay. my stock motor from ford came without a head gasket fitted , but passed all the tests. we all have had a bad days behind the tools
