Why isn't the 351C more popular in Cobras?

Jac Mac,

The 351C seems to be reliable in a race series, I dont know what the in between meeting maintainance is, or whether you could go a whole (eg 6 meetings) season, and if everything went smoothly, like no over rpms etc, before doing a freshen up!
Another point with a serious mumbo engine is even if its in a heavy car, like a Falcon as compared to a Cobra the weight doesnt seem to hamper it that much, plus the Falcon being a bit longer in the wheel base than a Cobra, may help to put all this canted valve big hp to the ground. I think that car was running Dunlop slicks, whereas the Shelby GT350 GW plus engines had grooved slightly less race dedicated tires. Like a lot of historic style racing the powers that be are trying to put a cap on modifications, tires etc, I dont rate myself as being in the league of these guys with their budgets equipement etc, but with me using a Yates headed windsor engine I guess its still within the spririt of the original concept, and going with the Jerico five speed should be okay, as some of those cars have 6 speed sequential Hollinger race boxes and approaching 900bhp like the Monaro!

I sort of think at times I should have stuck with the original idea of an all alloy FE 427 of around 550-600bhp through a nice TL 4 speed, but the Reynard space frame doesnt lend itself to that large engine, and it wasnt that easy to fit this great wide headed engine in the hole either!!!! Drive ability may suffer with my choice as Yates heads and low down power dont seem to be in the same sentence, but I guess I dont have to drive it hard all the time, and doing 3000- 3500rpm down the highway should be okay on a fun basis!

Excuse me for digressing a bit toward racing etc but thats what the 351C and Cobra is all about!
