3100/3.1 hybrid Pushrod Measurements?

[3XTurboAgain]

Does anyone have pushrod measurements for a 3100 hybrid? Im using a '90 3.1 Turbo motor with flat tappet cam and it seems my pushrods are going to be about 1/4 inch longer than 3100 pushrods. My pushrod checker tool is too small for the intake pushrods so im stuck. So far i have 6.281 inches for the exhaust but would like to cross reference with someone whos been through this. I need to get as close to the thousandth possible so any help is much appreciated. Im tired of riding my bike to work!

peddle bike? lol

well everyone allways ends up with a different mesurment
but maybe a couple people will throw up what they mesured for thier application so you can get a general idea.

id say mine but i cant remember and i didnt write it down, sorry man
i do remember though that i used ford 302? for either intake or exhaust as it was perfect

I asked a similiar question about my 92 3.1. No turbo but I'm assuming it's the same thing. People have measured between 6.25 and 6.275 for exhaust, and 5.94-5.95 for intake.

Here's the thread:

when i did mine i just used the stock gen 2 pushrods they worked well.

OK thats what i needed. Ill just go with 5.95 and 6.26 because my heads arent shaved and im using stock head gaskets. So Taz, did you use stock gaskets and what lengths did you go with?

and yes it is a peddle bike

I just want to be sure so I don't screw you up, is that the stock cam that came with the motor?


My head aren't shaved either so I went with the same numbers, 5.95 and 6.26.

I'm not doing the swap till sometime next month so I haven't bought the gaskets yet, but, I think I read somewhere that there is a head gasket for the iron head 3.4 that can be used on the newer 3400 to raise compression a little bit. I am not 100% sure if it applies to us, so I am going to search around for it when I get a chance and if I don't find the post, I'll ask in another thread. I want to make sure the thinner head gasket won't cause a problem with the LIM being off, and not sealing right.

As far as the manifold gaskets go, I believe someone makes a metal gasket to address the problems with the leaking LIM gaskets on these engines. It might be fel-pro, I'm not sure, but I know I saw it on the autozone website. It's a bit more expensive, but worth the extra cash in the long run. That will probably be the gasket I go with for the manifolds.

Hey Taz, hope you see this post, the 5.95s seems to be alright, but the 6.26s are way to small. it will probably be a 6.28- i remember getting that number when i tried measuring before. Ill let you know.

[TazMan]

really? 6.26 was too small? The highest measurement I saw from anyone on that was 6.275 on shaved heads, which was why I went with the 6.26 Oh well. Hopefully the 6.26's I bought will work out. I'll know in a couple of weeks.

As far as raising compression with the head gasket, I forgot your motor is turbo so nevermind on that.

what kind of cam are you using? profile wise, i was just wondering b/c i'm doing a hybrid aswell and i'm using a very lumpy cam so if those meassurment would work for me. that would save me some time

Any news? Did everyone use stock cam too?
