im new to inliners so i have some questions - 05/22/11 08:45 PM
Hello everyone.
Like I said I am new to the inline 6 engines. Have done mostly sbc and bbc's.
So I have some questions. I am finishing up my 496 and am tryin to figure what I want to do next. My machinist had mentioned an inline 6 would be cool and different so here I am.
This is were your all's advice and experience comes in.
My possible plan:
Use a 250 block with a 292 crank.
Turn the rod journals to 2.00 so I can use the 5.7 rods out of the 250.
Bore the block to 4.0 bore and use a 6.0 rod 327 flat top piston.
Here's my math:
250 deck height is 9.150"
Half of the 292 stroke is 2.060"
The pin height of the 327 pistons is 1.385"
250 rod lenth is 5.7"
So 2.060+5.7+1.385 is 9.145"
So the piston would be. 005" in the hole.
My concern was the clearance between the piston and the counterweight but I was told I could turn down the od of the crank on an engine lathe. Which also would help with the balance becaue the rod/piston combo is alot lighter.
Now am I way off with this or can this work? I have some the pieces already but if it wont work then its back to the drawing boards. Thanks.
