re: 2L hotrod cam quandry



It's my understanding that the Euro cams aren't designed to work very well with Spica and vice versa. You're probably right that you need some sort of hotter cam to make the most of your engine mods. I'd suggest talking to Wes Ingram about a set of his high performance cams that are designed specifically for Spica engines. You'd probably benefit a lot from one of his modified Spica pumps, too.

Subject: 2L hotrod cam quandry

I built my Berlina with the Euro spec cams, 10:1 flat top pistons, big valve
conversion and a mild porting job. Spica, not carbs. It runs well, has good go
but I am not particularly impressed. I drove an Alfetta with a Shankle 6 or 7
cam in it (none of the rest of the mods I'm pretty sure) and the car went
like blazes! Power started very strong at 3,000-3,500 and was way faster than my
car to 4,500-5,000. I was surprised partly because I thought my Berlina was
lighter to boot!
So I'm thinking I might have under-cammed the car, and I run across an
"Evoluzione Due" cam for the 2L engine with 12 mm of lift. I have to check with the
guy who relieved my pistons to clear the big valves to see if there is likely
enough clearance for the extra lift, but I'm also worried about whether I have
to worry about tangling the valves at overlap. Does anyone have any
experience with these cams, or reliable rumors to pass along? Likewise for the Shankle
cams. It IS a street car, but I drive it like, well, a "sports car" and strong
midrange makes a car fun on twisty roads.
