Dan,

I'm no expert, but the 370 Block {4.063" Bore x 3.563" Stroke} was a slightly different
animal than the longer-stroked 1959 and later Pontiac engines.

The 'Fuel Injection System' was built by Rochester, and was very problematic
on the street, as well as adding $500 cost to the Dealer Price of the car.

Only 500 or so of the 1958 Pontiac's were produced with the 'Fuel Injection' option.

Despite problems on the 'Street', the guys at the Drag Strip could really 'dial-in' the
'Fuel Injection' unit, and get those 370's to fly.

The 'high-performance' 370 had a 10.5-1 Compression-Ratio, and there were several
Camshaft units available.

Also 'High-Rate' Valve Springs were included with the more radical bumpstick,
as well as 1.65-to-1 Rocker Arms.

Pontiac provided the 'special' Camshafts and they had 'special codes'
*) "886"
*) McKellar #6, #7 and #10

By 1968, these engine combinations were heavily protested by the competition, and in
1969 NHRA deemed several of them as 'illegal options'.
