I,m about to start up my stroked 409 for the first time. Its got a roller cam and valve train and I was wondering if I have to break in the roller cam the same as a flat tappet cam. Doe I need to keep the RPM up around 2500 to break in the cam?

no, but I would keep the rpm above 1700 for a few minutes while adjustments are being made. Slow the engine down as the tune settings are found.Hope you spent a few dollars on th e valve train,,,,

The engine was built at Howard Race Engines in Barrie, and is a 30 over 409 block, balanced etc., Scat 4" crank, and H beam rods, Ross 11.5/1 pistons, Comp Hydraulic Roller Cam 511/521 with 4/7 swap, 817 heads redone and ports cleaned up, 3 angle valve job, comp cam springs, Harland Sharp roller rockers. I used the 817 heads rather than Eddys so i could keep the old school look of 6 Holley 94s.
I had a little set back and had to order a new fuel reg today. The original would only go down to 4 psi and I need to regulate fuel pressure at 1 1/2 to 2psi max or it will overpressure the carb needle. Just a couple days till I get the right one!!

I guess that didn't answer your question. The roof is chopped 4" and a Volvo station wagon donated its roof for the fill-in. Its channeled 4 1/2" and the rear wheelwells are raised 2"" and tubbed 5". The firewall is reversed, doors are suicided and flush fit.
