pushrod problem + cylinder head bolt problem
-changed gm heads with merlins and pushrods are short now
what to use? -cylinder head bolts are long for merlins -what to use? pls help or shoot me! |
Merlin should be able to tell you just what bolts you need to use. Canfield supplied the different necessary bolts when I bought their heads. I already told you about the pushrod thing. Go back to your earlier post. --- Jer

yes i remember
how to reach merlin? do you have www adres or phone number? thnx |
Well, I am not using Merlin stuff myself and you must have gotten those heads from someone who does. Hey, OSO guys; can you get in here and help Tim out with his his head bolt length prob.??!? - Or the web site for Merlin? --- Jer

Timucin,
Please list exactly which Merlin/Merlin II head, Iron/Aluminum, Part # and the block youre installing on Mk IV/V/VI. Thanks, Bob |
pushrods;
my calculations says; intake 7.800 exhaust 8.600 does it sound resonable? |
How did you arive at the calculation. I do mine using a checker push rods and machinest blueing on the valve tip. Then roll the cam around a few times to check the contact patch. also i check the lift on each valve with and with out valve lash before and after I replace the checker push rods with the new ones
|
I to am showing world part #073010 for the eight bolts and Manley part #42102 for the washers.To check my geometry I got the plastic gage that manley makes at the speed shop that slips over the rocker stud and you use a feeler gage to check the difference and all seemed to work out well for me.:cool:
|
turbo2256; i also ordered pushrod length checker but , it came wrong
i cut and rebuild one for myself, then did the same things like you did and here is the results -7,800 intake -8,600 exhaust but i cant find these sizes... i finnaly spoked to crane cams after 19 minutes of call waiting they say that they have to custom build ..... |
cylinder head bolts:
first arp package was wrong second i ordered with the number is wrong now will order the third..... today is not my day..... |
Did you try www.manleyperformance.com sight to see what they offered on the push rods?
|
nope
thnx for the link |
Floridian;

http://www.worldcastings.com/tech/me...ylindehead.doc
here is the link it says use arp-135-3603 bolt kit, i already have but they dont fit?!?!? my engine is mark IV,yep i am very sure cause checked the casting number etc. yep my heads are merlin,it writes on them, part number etc,is ok what does this mean?!? strange isnt it? |
I ordered ARP headbolts recently and had to add an extra washer underneath the headbolt's to make it work. I have a mark VI block and the bolts were running all the way to the end of the hole. i wound up cutting an 1/8" off the threads and re-tapping the end. It all worked out fine after that.

Push rods custom length try Crower.com Compcams.com Luniti epw.com dealer for above |

strip ;
i know that sounds stupid but i didnt ask the price , because its around 8-10$ each. plus fedex is about 120$ i am expecting something around 300$ max. the guy was were friendly and i was in a hurry we talked too much, he said ok to all 'special shipping details ' like friendly-custom-decleration invoice etc.. i dont expect something too high from him we'll see |
Originally posted by timucin i have to put three washers to fit, one is standard from arp two may be three : i don't want to do that... a bit confused waiting reply from arp I wonder if the merlin heads are a early design that doesn't have the raised exhaust ports ??. Just a thought? I bet the shipping is the worst part of ordering and import tax.customs keeping your stuff when it comes in. We take it for granted how easy we have it here. Good luck if i can help further let me know. Rob |
yep probably early design .....
cause i got them from a friend here in turkey,he said he bought them long time ago from cobra racing,when i called cobra, the person Mr Andy or Randy i dont remember the name, remembered the my friend but also he said long time ago.... thnx for help -what do you think about my gear drive post? |
