Seven Machine Shop: Cylinder Head Resurfacing

Our high performance engine has all the features of our standard engine, but comes with a fully ported cylinder head, high compression Cooper S pistons, performance cam, ARP high-strength head studs and rod bolts, and flywheel assembly. Each engine is balanced. Power output will be significantly higher than the standard engine, with a power band between 2000-7000 RPM and a slightly lopey idle.

The same careful assembly practices go into our stock rebuilds as our championship-winning race engines. Included in each package is a fully bored and rebuilt 1275 A-Plus engine, rebuilt rod change transmission with 3.44 final drive, reconditioned one-piece pre-Verto flywheel and clutch assembly.

For those of you who want more power, we offer a Big Bore 1380cc power unit. It has 73.5mm Powermax squeeze cast pistons, Keith Calver big-valve ported and polished cast iron head with dual springs, Elgin performance cam, ARP rod bolts and head studs

For those of you who want more power, but without the peakiness of a high performance package, we offer a Big Bore, high-torque 1380cc power unit. Includes all the features of our 1275cc standard engine, but bored out to 1380cc and fitted with a 3.1 final drive

Rebuilt completely in our machine shop, this head will include all new exhaust valves, guides and seals. Unleaded exhaust valve seats are installed. Springs and intake valves checked. Resurfaced
