I will see what I can do... which translates into asking Tensandtwenties to do it for me since I am just barely computer literate.

I have run the double valve springs before. I feel I should run them again in this engine but... um, well, I guess I don't have an excuse why not.

Hicost! Funny. No I took it out of the Seven when it was too loud, buzzy, high-strung, and generally annoying. It is now in a B-210 called Lil' Wiggly... and proved to be too loud, buzzy, high-strung, and generally annoying.

Oh, I see that in the tech wiki now. Ok, to be perfectly honest, that 1/4" (6.35mm) was a wild-ass guess, based on observation from across the shop, while being held back from smashing the crap out of something.

Yes... well, we hope that is the issue. We think the ports are just so huge now that they don't have any gas velocity until the revs are way up there. I know who built this bottom end and don't really want to grenade the thing. Not to mention, I don't like sounding like I'm flogging it for all it is worth just to keep up with a Subaru Justy.

The engine is a 1400 so I'm not sure if another 100/200cc would help all that much.

I am glad to know that I'm not crazy and that the valves ARE in fact shorter. I just wish I'd known it before we assembled everything.

An addendum to the tech wiki might be in order. I'd do that but I'm just barely computer literate, as y'all may remember.

First off, sorry I've been away so long. I have no excuse.

Now, on to my question/observation/issue:

A few years ago I had an H95 "Small Oval, Shrouded-Port" head ported within an inch of its life. It is beautiful. It flows ridiculous numbers. It is totally worthless for a street engine. Last week I decided to remove it and put on a "stock" oval port head to try and make the car driveable. My plan was to pull the valves and springs from the super hot rod head (aka $1,000.00 Albatross) and put them in the unmolested oval port head. (Sorry, I don't have casting numbers at hand.) Well, to my surprise, the H95 "Small Oval, Shrouded-Port" head appears to use a much shorter valve and spring package than other A-series heads. Like 1/4" (0.250" or 6.35mm) shorter! Do I have some weird bastard of a head or or has anyone else come across this situation? Is it possible that, since the ports are so badly shrouded, NO ONE has ever done anything with this head?

Fortunately, in all my hoards of junk... I mean spare parts, I did find a full set of "long" valves and springs and will be able to build a decent stock head for this engine.

Unfortunately I didn't discover the valve issue until the head was installed on the block and we went to install the rockers. (Hint, if your valve lash is 0.250" [6.35mm] instead of 0.010" [0.254mm] you may have the short, H95 "Small Oval, Shrouded-Port" valves in another head.)

I agree with the rest of the folks who have replied. When I swapped from the single Weber 40 DCOE to dual Hitachi SUs on the Seven, it was like a night and day difference. Lots more torque, better driveablity, and stuff like that. I want to say the "intake honk" sounds better as well, but DCOEs are known for a sweet WOT rort.

Gosh! It's Napoleon Dynamite doing whatever he feels like!

Paid five US dollars for a somewhat rusty 1200, sold it within 24 hours for $50.00 then traded a B-210 for it and $500.00. It took a tank of fresh gas, cap-rotor-wires-plugs, and a new battery to make it run. It was our "shop whore" for quite some time until it burned (burnt?) an exhaust valve. Somewhere in the photo section are pictures of that engine after all the machine work was done. It is back in the car now and should be running sometime, um, this year?

It is a replica of a Lotus Seven Series III by a South African company called Birkin. They usually run a Ford Zetec engine but I had to use a Datto. Mine has an A-15, or at least the bottom end of an A-15 right now! I run the dual SU GX intake setup and figger I got about 110 or so horsepower. We ran the car across the scales and it weighed 1150 pounds. Let's see that would be, um, carry the two, 522.73 kilograms, give or take. So it's fun to say the least!
