Sehr Performance Machine / Ryan's 350 Pontiac
Ryan dropped off his 350 Pontiac long block along with a set of 400 Pontiac
Ram Air cylinder heads, an Edelbrock intake and his Holley carb. He wanted
us to put it together for his '69 Firebird. His engine came to us with
blow-by issues from a broken piston. First off the cylinders had to be
relieved to clear the valves on the Ram Air heads. The heads were milled
to reduce chamber size and valve to block clearance was checked one more
time. All of his parts were inspected and magnafluxed to be sure we were
starting off with serviceable parts and the clearances were brought back to
low side of factory tolerances, a new custom COMP cam and a distributor
curve kit were added along with some other touches, the engine was painted
Pontiac Blue and bolted to our Dyno. Ryan is very happy with
the end results and is looking forward to getting it back in his car and
having some fun with it.

Pontiac 350 - 350 Horsepower For Less Than $500.00
A short video describing the modifications done to the 65,000 original mile
Pontiac 350 engine in my 1975 Formula. Using heads, cam, pushrods, rocker
arms and an intake that I had laying around, this Pontiac 350 developed 353
horsepower and 385
lbs/ft of Torque, for less than $500.00 invested.
My Pontiac 350 on the run stand. It's got a rebuilt Quadrajet, Magnum 280H
camshaft and some other stuff that I can't remember. Sorry about the poor
quality, it was taken using a cell phone camera.
On headers it's LOUD. You can barely hear yourself thinking.
