You can run a HT383E with factory intake...just need to tune PCM for 383 vs 350 fuel tables. Would be advisable to upgrade your transmission if you haven't also.Wow, I guess it would be safe to say that doing the Marine intake swap on these trucks AND getting the most out of it by using the 0411 would put the cost well over $1,000 if you add in the cost of the intake, new injectors, PCM, tuning and various odds and ends.
At the end of the day is it worth the money and labor?
Ive always pondered about doing a HT383 but the intake always seems to come up.
