Vogel Manufacturing S/A 252/ 300 complete roller set up will run about $600 if he does not have in stock I can fix you up, have 2 on the shelf or just go to isky catalog and look at short track profiles and have somebody grind one for you.
ran this cam for 3 years and very strong and broad power band, A lot of racers using this cam they just wont tell you!
I've used that same cam from Vogel for years as well in BP and FXT engines. Works great! It builds great bottom end power and torque so there's no need to turn it over 8-9,000. If you want a higher rpm engine with tons of mid range and top end HP, run the 385R260-7. Just make sure you have the correct valve train to handle the roller cam
