i am looking to buy a 383 stroker kit for a TBI 350. i looked on ebay and found this company called mad dog and the rep gave me a kit and all but the numbers sound kinda crazy. first of all the cam he offered at first was for .485 lift and 244 duration and this is for a TBI. then he also suggested 10.5/1 compression so im not sure if i can trust this company. I told him i didnt want to go that high so he offered a cam w/ .447 and 222 duration and pistons with 9.5/1. the kit balanced and shipped for $1400. anyone have any suggestions before i make a big mistake?
