Greetings all!

Okay it's been a while since I've put a cam in and am 99% sure I got it right. With that said, 99% when building a car like this doesn't meat $hit to me.

I want to install the cam straight up. I don't need to advance it at all. It is on a 115 LSA and is going in an AES 390 motor and will be fed by a YSI with AFR 225's. I have a rollmaster and there are two dots on the crank sprocket. I lined the first dot with the crank notch (this is the center notch on the sprocket) and then the back notch, on the tooth, lines up with the upper sprocket correct? Thanks in advance!

BTW, I might need to rotate the crank around a bit and this is a brand new shortblock. It's not a problem if I do that right? It's not going to hurt anything right? Thanks again everyone!

As long as when your al done the crank is at TDC compression stroke on the number 1 cylinder (dot on crank in the 1200 position) and the cam sprocket dot ( will be in the 6 o clock position) perfectly lined up with the crank sprocket dot, you will be ok.

OKay. If I am looking at the motor...the dot on the tooth of the lower sprocket is at exactly 1200...and the first cylinder on the RIGHT side of the motor is all the way up. That is the #1 correct?

Also, is it okay if I rotate the crank around with it being a new motor and all? Thanks again for your help!

Yes that's exactly right.

You can spin the engine as much as you want as long as its where its supposed to be when you install the cam and gears.

Obviously once you get the cam and gears installed and timed correctly you can rotate the engine over as much as you want with no worries.

Cool. Thanks again for your help MVP!

No problem brother!

BTW can't wait till you get done with your car it's gonna be a rocket ship!!

what block is that?

I don't have the answer on the red Oring, but somehow GM went nuts with different colors and sizing on pickup tube vs Orings. Your most likely aware of that already.

I got the cam tooth wrong once. Not my best moment. It is a lot harder in the car.

Not sure if you read my entire post but...I never said anything about the o-ring.

Yeah this is definitely why I wanted to make sure it was right lol!

Bret BLOWNBLUEZ06 did a post not to long ago on this problem with doing the cam like this. 100% you will be fine here but without dialing the cam in it will be a few deg,s off. You will loose a few HP doing it like this but 90% of the builder does this same way.

But Bret did the same as this then dialed it in with a wheel and it was off just a few deg,s... Robert

True if you can degree a cam it's a good thing and can't hurt.
