First thanks to everyone for all the great info on this forum. I am finally at the "fun" part of building my 1980 Buick Regal pure stock....the motor. Here is where I need some advise, long story short, I bought a pure stock from a guy I know complete with motor, tranny and all the goodies. The motor ran great before I pulled it out of the car, problem is the motor is bone stock (I mean the cam, and every thing ). In the class I am going to run in the only thing you can do to the motor is put a cam in it (.420 lift max) so that is what I intend to do. Trouble is I have a couple of friends that race motofied and they are trying to give me advise. They say to get the block boiled and have the machine shop install the cam bearings (so I know they are done right). This does sound like a good idea but is it neccesary? I just want to freshen up the motor ( main/cam bearings and new rings ) and put the biggest cam allowable in it. If I do go to the biggest cam allowable (.420 lift max) is there anything I else I need to do to the motor to except that cam? Last one, is there anthing else I would look to replace while I`m in there?

Thanks for any info

yes timing set and put good rings in it

remember that the cam is what makes or brakes the power out of a motor so pick very carefully

and just have FUN that is what this is all about

drive hard or drive home
good luck

Take good look at the balancer.They have a bad habit of coming apart on a 305.

The Iskyidiarian LR3 is a good low lift camshaft to use. I had one in a 305 a few years ago and won 6 features in a row. They cost about 120 bucks but, In my opnion it is a very good low lift cam.
