Here's a mild 350 combo I put together for a '69 Firebird that my brother owns, a heavily optioned car (A/C, power discs/steering/windows/drivers seat, deluxe interior) that weighs over 3700#.
350 bored +.030
1969 400/428 #46 heads, cheap valve job/used stock springs, press-in bottle-neck studs
Crane blueprint 068 cam (212/
[email protected],.407"lift) advanced 4 degrees running stock 1.5 rockers
Cloyes Tru-Roller timing chain set
Stock 1969 iron intake, exhaust crossover still functional
1972 400 750 Q-jet
91 octane premium unleaded (9:1 compression)
Stock points distributor
Stock log exhaust manifolds, cheap 2-1/4" dual exhaust
TH400 trans with shift kit
TCI Saturday Night Special converter, approx 2500 stall
1980 T/A 10-bolt 8.5 rear, 3.42 posi
235/60-15 street radials, no traction devices
This car ran a 15.21 ET at a 2800 ft. altitude track, launching easy so as not to spin the tires. Using the standard correction factor for this track the ET at sea-level would be in the 14.80s.
All stock or stock-replacement type parts were used for this engine build. The 068 cam was chosen with .407" lift because of the press-in studs. I didn't want to overstress the valve train and I wanted the simplicity of using the stock 20# valve adjustment procedure (actually no adjustment, stock non-adjustable valvetrain).
A no-frills 350 built on the CHEAP and a decent runner.
