new at this have question about engine blocks

stock eliminator · 10-10-2008, 08:49 PM

I was wondering if you can bore out lifter holes and put in larger lifters and/ or put bushings in them. Question two can i put 4 bolt mains in a 2 bolt main block. Question three can i use a gridle on my mains to tie them all together. Question four can i use tubing to redirect the oil back to the oil pan. Question five can i use a windage tray. This is for a 1986 J/SA 305 Camaro NHRA rules thanks

1. Bushings, yes. Larger diameter lifters, no.
2. Yes, but you won't need them on a 305 Chev.
3. See 2 above.
4. No
5. Yes

OK. Thanks for the info i really needed those answers. Forgot one can i put small tubing in lifter valley in those holes where oil drips down on cam and crankshaft. Or can i plug them. thanks again

Yes.

Going back to your first post, if you want to build a strong base for a 305, start with a 350 4-bolt block and sleeve it back to 305 bore size. That work is no more expensive than adding 4-bolt caps and a girdle to a 2-bolt block and will benefit this combination much more than all the crank containment work. When was the last time you heard someone spitting a crank out of a SBC Stocker? When was the last time you heard someone complain about ring seal in a SBC stocker? 'Nuff said.

Dwight,
Six or seven yrs. ago I did the 350 4 bolt sleeved 305. After all the work was done on the block I was told by NHRA that was not legal. My question, is this a legal modification now. I think I got 2 cases of beer for it?

Buy a small bore bow-tie block. You will still have it when you're ready to quit!

Dwight Southerland · 10-11-2008, 11:56 AM

I assumed that it was legal since there are so many sleeved 454s masquerading as 396s. Seems like last year in discussion the 4-bolt is not legal for the 305.

Bruce, you are exactly right!!

Well i want to thank everyone for all the info. And i know everything i asked is overkill. But that's who i am. I will do a 200 percent effort to be the best. I'm just that way. thanks again

While we're on the subject, is there really much to be gained by indexing the lifter bores on a small block Chevy? I thought they were pretty darn close to right-on from GM.

I'm no expert on chevys but I'm under the impression the exact opposite is true.
