Lunati Voo Doo
hey buddy i dont know exactly what the guy told you but i have personally bought and installed 1 in a flat top 355 with stock 186 double humps. its a stock bottom end motor with hypertonic pistons and a victor jr intake and holley double pumper. the intake is a little much so im switching to torker 2. its is a lunati 276 adv duration .504 intake lift .525 exhaust. the engine was in a 80 malibu with a th350 with a STOCK stall(hurt it alot) but other that the stall the engine itself sounds great with the cam, all my friends are jealous, with out the stall its not great off the line OF COURSE and with stock gear but that little engine is a missile once you get it into its proper rpm range. it has no problem gettn over 6000 rpm even with the not so great heads and pulls great all the through the rpm range. i would suggest it to you, sorry to ramble hope this is a little insight for you
