your right in going roller, you cant lose there.
seeing as how you have the software you more then likly know better then me what cam will work for your needs
Id just tossed 249 cam in my tbi 350 and let me tell you its pulls alot harder from idle to the upper rpms where it seems to kinda sing off. well I guess I cant atribute that to just the cam as its hole new motor in the truck. the engine i worked over was a roller block and it tore me up to go with a standerd cam, just couldnt come up with that kinda cash to get the roller cam and roller lifters.
damn it would be cool to have roller vavle train from the cam to rockers. sonofa, lol one of these days I guess,
turbo city has a MAP adjuster alowing you to run alittle bigger cam and still keep the computer happy.
also if you know someone in the right place you might be able to get the roller set up for far less then 600 bucks.
I think if I had it to do over again Id go with a slightly bigger cam and get MAP adjuster.
though ounce I get some lower gears I dont think its going to feel like the same truck, planning to regear just the rear to 4.56 and be 2wd for awhile.
anyways Ive strayed way off the subject,good luck with your decision
