I have a set of 882 full ported heads that some one spent a lot of time on . Do you guys think I will need to run head studs with this small blower . I am not sure what lbs of boost this 144 blower puts out . I dont think it will do more then 14lbs .

There are to schools of thought.
One is under boost the A/F will get there no matter what with 6-8 lbs. of boost.
I have seen on the dyno with a 383, hyd. blower roller cam,8.5 to 1, with well ported double hump heads and a 6-71 blower.
This combo. went 518 hp.
The second idea is a great flowing head will really help the blower work easier.
Then we bolt on a set of 195 cc CNC ported heads from AFR.
The new combo. went 634 hp.

What about cam, what is the rule of thumb there... 383
I believe I read that the 144 will work with 10.5 cr pump gas, high test for sure
