Hi. I am building a Ford Mustang road racing car. The engine I am using is a 302 Ford race engine bored and stroked to 363. It is a dry sump engine with about 800hp at 8500rpm with max rpm at 9200. I am trying to find the right oil in the jungle of oil brands out there.. Lol.. There are 4 types of oil I am thinking about, Lucas 15- 50 racing oil, Amsoil 15- 50 racing oil, Royal Purple 15- 50 racing oil and Castrol R40 (castor based). The Castrol is single grade 40 castor based, but I think it will be fine if I just keep the oil temp whereit should be. What to do, and what to use?????
Thanks guys!!
