Somebody show Tony a vid of Bob G's 427. Maybe where he runs 135mph 1/4mile.

The stock stroke is 3.66 when ground it ends up at 3.75. It can be pushed out to 3.80 on smaller Honda 1.890 journal. I have not done this yet. Crank guy said lot's of meat in the LT5 crank to cut. The BIG Bore is from AES 4.165
The cheap stuff is to keep it down to 377-382ci mostly off the shelve stuff.

OOOOOOh men this is the secret !!!!! an offset 2” rod journal .

Interesting to know if a stock crank have a rod journal damage can be offset regrind to 2" and go to 2" journal chevy rod.

The BIG Bore from AES 4.165 only for BIG POCKETS $$$$$$$$$$

"It can be pushed out to 3.80 on smaller Honda 1.890 journal "
This engine is international !!!, England (Lotus) design, Usa (GM) paid $$, France (Carcassone) presentation, Japan (Honda) Internal powered, and porting and tuned by enthusiasts all over the world. And only 6.939 where made

I will post a revised LT5 stroke PDF

What's wrong with 401ci's for $10k completly done short block.

Closed deck,new pistons,new rods.crank offset to 3.75,bore 4.125 and can use stock head gaskets.

If you go with bigger bore where do you get head gaskets?

you go with MLS gaskets and tell them the bore size you need.

Ok,i would think they are a bit pricey,but as long as we have something.

Heck then we can make a 454ci

3.750 x 4.390 454

I don't think the block will go that far out

Daryll went with the MLS gaskets on the 380. I think they were $350 but reusable.

Car has been running great. 2 issues.....leak at the front of the motor, not the pan. Thought it was the oil filter housing, but starting to wonder if its the front crank seal. I am seeing oil dripping from the trans inspection cover also.....

Thought it was solved yesterday as I drove it with no leaks. Today I ran the car up to 5K....and leaks...starting to think its the front/rear seals.

Any thoughts?

Leaks are wet spots....no large puddles, etc.

Happened too many times to be residual.....

Everything is new and rear seal torqued to spec
