421 HO engine
 

Looking for advise as to what cam and make I should I buy for my motor. I’m boring the motor about .40 and would like to stay with a HO cam. Motor is original just want to beef it up a little and be able to drive ever day and enjoy. Have the original 093 HO heads too.
Thank you

I put a 068 in my 421 HO.Tom

Thanks Tom how she run? Putting this in my 67 Catalina Wagon with Tri-power.

Runs great, 4 speed car with a 2-4 Bathtub tunnel ram in a 62 GP.Tom

This is an Ultradyne Cam I ran in my 66 421 HO 9 passenger wagon. It was wonderful. Smooth idle, lots of vacuum, smooth enough idle for AC. Ran 14.61@ 96 MPH at almost 5000 lbs. My car had a 400 Turbo and a 3.42 gear. I would guestimate 20 or so HP better than an 068.

If interested, call Bullet Racing Cams, ask for Tim Goolsby. He can grind one up for you. This is a custom grind. Tell him Mike Garblik sent you.

Thanks Mike for the information sounds good. I will contact them if I decide. Appreciate your help.
What’s a cam like that going for? I would imagine over $200.

Less than $200.00 for a flat tappet cam last time I bought one. Just got a SBF cam from them. Something like $160.00-180.00 to my door as I recall. Nothing crazy. Tim is a little hard to reach on the phone. Be patient and leave a message if you have to. Good luck. Google Bullet Racing Cams. They bought Ultradyne when Harold Brookshire passed. Tim worked for Harold for decades.

Thanks for your help Mike

Have another question about my motor the machine shop told me today they need to bore it .60 now because it was bored out at .40 before. My question is will that cam we spoke about be ok boring it to .60 or do I need something different?
Thanks Peter

I can jump in on this also,If getting custom pistons you only need to bore enough to clean up the bore.Tom
