Hello everyone,

I recently wiped a lobe or two on my 330 and was looking into upgrading to a roller cam setup. I searched and couldn't find too much on here for the 330. Pretty sure mine is a 67 block and has the #4 heads.

I was looking on mondellos site and I like the specs of this camshaft for street use ->

RH-6-14 Hydraulic Roller Camshaft


$459.00

• Muscle Car Performance Cam, 800-4500 RPM Range
• 0.510 Intake lift /0.520 Exhaust Lift
• 252° Advertised Intake Duration / 265° Advertised Exhaust Duration
• 206° Intake Duration @ .050 /214° Exhaust Duration @ .050
• 110° Lobe Separation

Everything looks pretty straight forward on their site, until the lifters that are recommended for that cam shaft say "This roller tappet is .500″ longer than a stock tappet and requires a shorter, specially made pushrod" but there is no recommendation.

I understand that the 330 may have specific valve train components and this might be an issue. Maybe someone could point me in the right direction? Thanks.

Make sure it’s a ‘67 first. Then run the other way from from Mondello in Paso Robles.
I can get you anything you need to do the swap, happy to help.

Which "Mondello" site are you referring to ? There is a difference !!!!!!!!!!!!!

olds 307 and 403

His link is to Lynn the thief.

AH, that "Mondello", I see that now, I didn't click on the link before because my computer is running slow. Avoid the "Mondello" in Pasa Robles like a plague !!!!!!!!!!! Cutlassefi can certainly help you better !!!!!!!!!!!!!!!
..........Just my two cents worth.

Thats really good to know! Here are a couple pictures of the block and head casting numbers. Looks like a '67. Thanks!

Yep, talk to Mark (Cutlass EFI) and stay far FAR away from Lynn at Mondello in Paso Robles.

From the research I've done so far..

394417 casting number = '66-'67 330 engine with 39° cam bank angle

Could anyone else with more knowledge confirm this? I plan on getting the parts soon. Thanks in advance!!!
