I believe the bolt head size for the crank bolt is 1-3/16. I will have to check that. Fear not! Getting to the timing chain and cam is not difficult at all, just need to be very careful when working with those parts. Here is what you will need:

Balancer puller -- available at stores like NAPA.
Crank rotation stop -- I made a simple one out of 1/8 strap and a wood block.
Allthread rod for removing/installing cam.

PM me if you are seriously interested in the tooling.

 

tdrex- It is great to hear that your cam install was a success and you are very happy with the mods, especially the cam. Regarding the 0814 cam, where does it produce the most power in the rpm range? Is it more a low to mid range cam, mid to high range cam, or does it produce power across the rpm range? I was considering this cam but I was concerned it might be too big of a cam for towing and I would lose some low end. I like Hughes Engines a lot, I have their FI Airgap Intake and it is awesome, and now I'm considering either a 704121 or 704111 Crane Cam or the Hughes 9204 cam. Thanks for the updates and information regarding your cam and heads install. Very informative and gives me some guidance which direction to go with my cam install. Great thread.

 

for anyone interested in this awesome thread...

this cam was recommended to me by a performance engine builder.

Glad you enjoyed the thread!

Hughes advertises this cam's sweet spot between 1800 and 5500. I chose it mainly because I wanted a good mid-range cam. I'm not going to be pulling stumps with, but I do plan to tow a pop-up or small travel trailer. At the last minute, I decided to stay with the stock keg so I wouldn't loose too much low end. If I ever take it to a dyno, I will publish the results. After a few days driving it, though, I feel like I made the right decision. Acceleration and throttle response is terrific and there is a definite improvement going toward the top end.

 

race a hemi and let us know how you do! lol

 

hemi trucks lose alot of there power in the drive train. they are not very quick stock.

i must say, i have enjoyed this thread also.

 

Thats the cam I'm gonna go with. Comp said it would be good for towing, low to mid range, pass emissions.

Like I mentioned before my main concerns are install and needing an sct tune. I really hope to order my parts very soon. I keep putting it off worring about money and having everything I need to finish the job.

I still want a vid of yours rex

 

tdrex- Thanks for the reply. It is good to hear that the Hughes Cam is working for you. The information and experience you have regarding the 0814 cam is making me reconsider in getting that cam because when I tow, I'm usually in the 3500 to 4000 rpm range, sometimes more, going up some decent grades. I'm happy with my low end power right now but would like to improve in the mid range when towing my TT, especially going up inclines. Can't wait to see your dyno numbers. Thanks once again for the information.

 

hey Rex hows the truck running?

I'm getting close to start putting mine back together

 

good to hear that it is back together and running

I am not sure what is meant by a 'sweet spot' for a cam
but most of the auto engineers talk about the 'Torque Spread'
which is where the torque is within 10% of maximum

for example
if an engine makes 400 ft-lbs at 4200 rpm
and this drops to 360 ft-lbs at 6000 rpm at the high end
and also drops to 360 ft-lbs at 3000 rpm at the low end
then the 'torque spread' is
3000 to 6000 rpm
