Just realized I might've done a stupid thing...

Well, I might have done a silly stupid thing....

1 year ago I was rebuilding the motor I went ahead and bought a Cam from summit.

It was the Mutha Thumpr Camshsaft.

This is for a roller 1990 LA360, with flat topped pistons. estimated comp. ratio is around 9.6-7 to 1
I have stock 308 swirl port heads that have been milled a little.
with 1.5 Roller rockers.
Roller timing chain.
the bore is still 4.0 inches
(I was lucky and found a low mileage motor)
3.23 rear end. and 2200 stall convertor in an A999 tranny.

Specs for the Mutha' Thumpr: (Grind 291THR7)
Valve lift (std. Rockers) int. .522 Exh. .509
Duration: Int: (.050 in.) int: 235 exh: 249
Duration (Seat to seat): int: 291 exh: 311

*Should've realized then that might be a problem there Bob'

As I am putting the motor together, and putting it in the duster and getting it ready to run during my spring break. I'm staring at my power break system that I installed in the duster.

It dawned on me, I might have put in a cam that will not generate enough vacuum. I should've went with one of my first choices:
Lunati voodoo 20200710 or 20200711


So... My options I think is to ditch the power brake setup and go standard brakes. Or pull apart the motor and put a different cam in...
