i know this has been asked many times before but instead of seaching threw all the threads (i will anyway though), i though i could see if i could get some more direct help.
My plan is to rebuild my 350 sb and slap on some 062 casting vortec heads (i already picked some up cheap and had them pressure tested). I am on a budget but so is everyone else so i can see some people knowing where i can get cost effective parts. I have bad compression in one cylinder and found out using the oil test its one omy my piston rings, so i thought i would just go and replace them and the bearing (friend told me there are cheap and if i have to disconnect them from the crankshaft i might as well replace them too).
Now my plan is to also replace the cam but i have heard so many differeent cams are the right fight for the vortecs i dont knwo what to think. I dont want anything to crazy. A mild cam that is reliable but i want some kick too so i was thinking the lift to be about .46 and i heard that get close to the max the stock vortec heads can take but someone also said you can get a little more clearance if i get new smaller valve seals?
Also i now i need a new intake but what kind can i use? i heard there is a problem with stock hood clearance but i have a K&N drop base filter, am i okay?
the last problem i heard about was temp, sender will not fight into the vortec heads? is that true?



any more help from anyone that has done this before and just know something about it would be so helpfull. my engine is all apart and i wanna finish this little project within the next few weeks





thanks,


Jesse

 

I used the summit 1103 cam and the vortec heads. I am pleased with the way it runs. For the temp sender, you can just enlarge the existing hole in one of the vortec heads to 1/2 npt. Others have moved it to a hole in the intake manifold, but I prefered to keep it in the stock location.

 

okay, i thonk i would just wanna enlarge the hole too... any thing else i should be warn about and know???

You will need the vortec rocker arms which are self aligning. You will need an intake manifold and valve covers with the center bolts.

 

I'm feelin' so lazy, a better reply seems too much like work.

 

i wish you would not be lazy and help me though....

 

Jesse, I am not builder but that piston needs to come out the top of the engine. If the engine has a significant amount of miles there will be a ridge at the top of the cylendar from crud buildup. This ridge needs to be removed with the proper tool and the cylendars hoaned before you replace the piston. If not, you will blow the new rings pretty quick. If you are only replacing the rings, the ring grooves in the old piston need to be cleaned with the proper tool as well.

Good luck

 

I used a Lunati Voodoo cam, and the Jury is still out on it. I'll let you know in another week or so, once it's broken in under load.
