Questions on 2270 engine

Post by Ephry73 »

First of all, I have to say that this 2270 feels like a beast! while standing still and pressing down the gas pedal the car wants to twist and turn with the engine! Amazing! at high revving speeds it sounds like a small block V8 (with only 4 cylinders) :) The A-1 system just wakes this one up big time!
I currently have Weber 44IDFs on it.

I really like this engine, and still have to do some finishing touches. I do have some questions though, for an engine this size, should I be worrying about the idle jets being 60s? or should I tuned it leaner at idle?

Also, I am thinking baout timing. With the mallory Unilite I can basically tune it however I want, but want to make sure the engine starts right u, and also that the engine doesn't fry and makes the most power as well. Jake, this engine has your 912 special camshaft in it, what total advance and what idle timing should I be looking at? Just curious. This is Jason's old 2270 engine.

With the 12mm motorcycle plugs that are in the heads, what gap should I be running? Specially using the Mallory with the 45,000 coil.

Also, for an engine this size, should I be looking for heavier oil to use? currently using Castrol Syntec 20/50w.

I would love to get these questions answered, for I feel this is the engine that rightfully belongs in the Ghia. (for now )

Jake, if you can send me a PM that would be great. I still want to eventually go with EFI and improve the engine's intake that way.


Sincerely,

Ephry, did you buy Tom Perso's old engine?

Also, The Mallory will help the car run better at all RPM ranges, including start up and idle.

No, I didn't buy Tom's. I was going to last Spring though. When he posted it for sale, I had already made the deal with Jason M in PA.

I just have those generic questions about the engine, since he used a 2270 kit from you to build it. I was surprised to see no 911 adjusters though. :D

IT WAS NOT MY KIT!!!!!!!

I sold him a crank, rods and pistons and a cam- Not a kit.

BIG DIFFERENCE!

Yeah. I noticed that with the rocker adjusters. Well, not a kit, apologise for that missconception, just wanted to make sure. One thing though, the way the cam is setup, would it be ok for me to add my 1.7 rockers and 911 adjusters to the heads? The heads have huge valves and not sure about the springs. Just don't want to mess with the geometry too much. I was just wondering if the 1.7 rockers will be too much for the cam.

Also, with that camshaft Jake, is 30* total too much? Hate to bug you with all these questions, but now that I bit the bullet, I want to enjoy the engine. I do have to say, that engine does not hessitate at all, and feels super balanced.

Ephry,
Sounds like it's time to get on the phone with Jake and hash things out...and if you can, try and find out what other parts are in your engine. Good luck.
BTW, being in maryland, do you know Scott Gregory?

sounds familiar, but not sure. I bought the engine and took the heads off to make sure what the valve sizes were. everything else looks to be in order. I just want to make sure that I don't overtime the engine too much, or give it too little timing. All I could get is that the cmashaft is the same that was on Jake's 912. That didn't tell me much, as i am not sure what cam it is. For the money, this was a great deal, and Now I have a spare DTM that I will be selling shortly, with the surrounding tin as well.

Like I said, the engine is super strong and super smooth. I just want to make sure that when I do maintenance on the engine, I shoot for the right numbers. ;)

Since the entire combo wasn't mine I simply can't give you accurate information...

I'd say shoot for full timing between 28-32 degrees[/i]

Ok, that sounds about how I have it now. I left the total advance at 30*, just to be safe, seems to pull very strong. So, the 911 adjusters sould not be a problem with the rockers as long as l make sure the geometry is correct? Just wondering.

Can't make any assumptions.... Too many important factors that could cause issues and leave me to blame.

Nah, I won't blame you Jake. Just trying to get some clues on timing and maintenance. Been reading your posts for too long to blame you on anything. I do have to say, the balance feels really good in the engine.

Update: Engine is now revving smoother and down to 900+/- Rpms at idle. I think the idle jet is too rich at 60, but will do more adjustments and find out..... This thig seriously rips! I know I have stock tires and all, but I was sliding all the way into fourth! LOL

I love how it just keeps on pulling!
