Just got this spec sheet sent through from my mechanic, he sent my cam away for a regrind, I'm pretty new to engine building and don't really understand what makes a 'good' cam. Came in at about the same price as an IPD 'Street Performance Cam'. My untrained eye puts it slightly ahead of a 'D' cam, and somewhat similar to the big block chev V8 by 'Pauls Cams' on this list - http://www.1800philes.com/ianr/_superlist_grinds.html.



As far as the rest of the engine goes, it's got a 'big valve' head which has had the ports cleaned up, and all new valves fitted, IPD/Isky double valve springs, IPD hi-rev lifters and push rods. New pistons & rings, bearings etc to the engine. Will be having a set of 40mm Mikuni Solex dual throat carbs on a Weber manifold.

The engine is going in my 145S which is my 'daily driver'/fun car, would it be worthwhile looking at taking some weight out of the flywheel or is it best left as is for road use?

That's a fairly aggressive street performance cam, but a bit milder than what I'd call a Targa cam. 40mm carbs are too small -- you'll want 45s.

Those are great links George.

Not to hijack the thread, but @Phil, what's your typical lead time on a B18 build? Are you still building motors?

Tony, I am still building engines, but right now I have a backlog of orders and can't reasonably start any more until after the new year. The process should take three to four months -- there's lead time having pistons (and sometimes cams) custom made, and the head porting we do now involves welding that gets farmed out to a specialist.

Good to know, Phil. I'll email you separately at your VClassics address, if that's okay.

Figured I'd chuck this in here rather than starting a new thread.

Is the stock B20 a solid or hydraulic cam setup? My mechanic is saying the the engine is set up for a solid lifter arrangement, I've supplied him with an iPD hi-rev lifter/rod kit (http://www.ipdusa.com/products/6979/107880-hi-rev-lifter-pushrod-kit) and he's saying that they are hydraulic lifters and thus incorrect for the motor.

The cam is a regrind of a stock cam.
