I have a 68 olds 455 with C heads,rochester carb,stock cast iron intake,cast iron exhaust manifolds(may upgrade to shortie headers)engine in shop being bored .30 over,shallow dish pistons said to yield 10.1 compression ratio..probably in reality (closer to 9.5)....considering a mondello cam,MW-31,555HCR lifters,SK247SP spring/lifter kit,TR-252 timing chain...I have 3:73 gears and a 4sp auto tranny for it...Plan to use as a weekender...Looking input on cam selection given the info. provided on my application...The Mondello tech.support has suggest the above parts...This engine will reside in a 87 cutlass 442...want to use the power brakes and a/c...Does any of you guys/gals have any suggestions based on your personal build/experiences for a streetable cam with nice/lopey idle that wll work with power brakes and a/c ? Thanks, Don

 

The best Street/Power cam I have ever used in mild 455 is an Ultradyne from Bullet Cams. .499 lift both Valves and 226 In 233 Ex at .050 on a 110 C/L.

I have heard of some unhappy experiences recently with Mondello .

Just my .02

Danny, is correect. The cam the he is mentioning sounds great. MW31 cam is a w31 camshaft that is somewhat lazy and outdated. That is a great cam for a restoration.

 

For your combo I'd do an Erson TQ50, 228/235 on a 110, .504 lift on both.
Cam, lifters, and chain set to your door is $295.00.

This cam would pull hard and I guarantee you you will hear it.

Thanks

 

Thanks guys,,,,Cutlassefi, I am interested in your offer...I will need new springs also...to go with the new cam,lifters, timing chain etc. How much will that change the $....Don
