Does anyone know of any Templates i can down load and print off for my 350 block so i can clearance it for a 383 crank?

I herd they make an after market oil pan gasket to use as a template but did not know if anyone knew of a site i could download a pic and print it off to mark out my block.

Thanks!

The way it's done is to use the crank and rods you are going to use in the buildup as the template.

so just set the crank in place and mark where it will hit..hog it out and just keep repeating till everything has enuff clearance?

 

Yeah, that way you remove the minimal amount necessary, so that you still have the maximum area for gasket sealing. different rod/bolt combos need different amounts of clearance, so this is really the only way.

 

Put the crank in and the two rods for that pair of cyl's.Rotate it and mark the pan rails,remove crank then grind to clearance.Reinstall crank and rods,rotate then mark both cyls.Remove crank and rods and grind clearance.Don't grind bottom of cyl's to much you WILL grind a hole into water,Just for .050 clearance. Go to next pair and continue.
Remember keep the new crank and rods and brg's CLEAN during this grinding or you will ruin that set of brg's and scratch the crank. "O" you have to have the pistons on the rods.You need to keep them clean and free from shavings also.

 

Be careful not to go into the water jacket

 

question about a 396 stroker. do you need to grind anywhere else other than for rod bolt clearancing? any drawbacks to goin 396 stroker instead of 383? the parts are the same price, so why not? I know you need hbeam rods with capbolts to clear the cam in the 396, but anything else to look out for?

 

Sometimes even with h-beam rods with capscrews you still need a small base-circle cam to get the clearance you need.

 

There is nothing about an H-beam v. an I-beam rod per se that alters clearance. Where does that idea come from? I don't use any cheap rods, but for a moderately priced rod, the Lunati "Pro-Mod" rod (an I-beam) has good clearance, much better than the more popular (and a little less expensive) Eagle H-beam. Crower's are somewhere in the middle. The best rods for clearance that I have used are the Oliver billet rods, which are I-beams. Next to ZERO clearancing needed on a 3.75" stroke. I think it would be very easy to hit water with Eagle H-beams and a 396.

thanks rich, those are the kind of things I need to hear about when deciding what parts Im gonna get. I'll stick with the 383 if it is alot safer on that note. as for the Ibeam/Hbeam rod clearance, I thought I read that on strokermotor.com somewhere. tomorrow I'll be calling flatlander racing to try and figure out what Im gonna do. thanks for the tips though.
