I'd like to do a little more to this motor as far as longevity and durability so before it goes under the knife any suggestions?

I want to buy a 4.5 inch arm for it other than that anything goes.
It already has bushed lifters, the bore needs cleaning up and should clean up on .030 over. Should I go .080? I plan on filling the block regardless.
Pros and cons on bore size and suggested cranks to run as well as rods are welcome. I am sort of at a point where I can't decide on GRP aluminum or Oliver steel rods. Any thoughts welcome.

I plan to run a set of TFS heads on the motor for drag racing. Current induction set up is a Birdcatcher on methanol.

Cam suggestions?

I would first have it sonic checked. My C8 block checked good to .140 over. It's at .080, so it still has a couple of bore jobs left in it.

If it checks good I would go with .080 for 3 reasons.

1. When you say TFS heads I assume you are talking the "A" heads. These will have large valves (2.30/1.88 or larger) and if using a .030 over bore you will be shrouding the valves with the bore The .080 will open them up a little more.

2. Most of the shelf stock pistons you find for A heads will be in the larger bore/ stroke sizes.

3. Cubic inches. .080 and the 4.5 crank will be a 557.

For rods I would go with steel rods if your main focus will continue to be bracket racing. Oliver is good, but once you are up in that range I also like Carillo. The aluminum would be good for heads up, but remember they have a defined life span.

As far as block only items for longevity there are not many other things needed. Perhaps have it set up for O rings if your compression is going to be up there. Mine is O-ringed for nitrous use. That block, filled, will last a long time at the 1000 hp level.

Thats going to be one bad a$$ motor.
You might be able to keep up with me now.

65 coupe,351w,C4,Big Boss 429 hood scoop,8" 3.40 TracLoc.

Something around .770/780 lift (you can still afford valve springs at this level. Over .800 gets $$$$$)

280 to 285 @ .050

110 lca (112 might be a little better for juice)

Bascially a little larger than what I currently run due to the better A heads you will have.

Mine:
.770/.770 (.740 net after lash)
275/280 @ .050
110 lca
installed straight up

Sounds like a fun project.. You have definately woke up the big boys with big ###.. I think I even witnessed some frothing at the mouth.. I love it.. You guys are great..

Oh yeah guys.. His wife and daughter are his biggest supporters.. That's the best..

I love it.. and I love to be there the first time you fire it up..

Don I fired it up in the pits at the 40th, you werent there though. Some guys parked 30 ft from me started yelling and acting like complete jerks saying I was raining rocks on them. Some folks looking at the car laughed at him because his claim was ridiculous. I was parked WAY away from them just for that reason.
I really get a kick out of the lil kids eyes when you fire that bad boy up. They always light up. If you let them sit in it and get their pic taken by their Dad they think they just won the lottery or something. makes it all worth it.

Nope, I have Blue Thunder heads with the BBC exhaust ports. They flow pretty good, but are a step below the A heads. The only advantage they have over the A heads is that the BT's use regular SCJ parts, intakes, pistons, etc. So they are are bit less $$$ when you look at the whole engine.

The A heads require a different intake ($600) and pistons (different valve reliefs).

Yeah, that guy really did get his panties in a knot, didn't he?

Vikki did a good job stopping you from giving that boy an attitude adjustment.

Maybe have a role call and see, I like to know who's running a BB.

Anyway good luck, interesting build. I wish I had the $ support for 514.

I got my headers yesterday. The darn tubes are bigger then most street car exhaust pipe.

The UPS dude has been coming almost once a week and I have this stack of boxes for my Fox Mustang BBF build. I can't wait till it's running.

Take care!

Les Why don't you start a roll call thread? Most BBF guys are rather reserved, like me. LOL
While your at it tell us what you're doing with your BBF project.

He then said "why?" sooooo I'll be picking up my block next week and sending it somewhere to sonic test it. Anybody in this area got any ideas? I got one more guy that might have the equipment to do it, after that I'm looking.

Jerry, sounds like you have a typical stock rebuild type machinst that likes SBC's. There's about a 98% chance your block will be fine at .080, but it's worth the check. I'm not sure where you can find a place in your area. If not in your area, I'm sure you can find a place in Memphis. I know of a couple of places in Hunstville, Al.

I just hope to get my stroker cleveland done before I'm 40.

I'd start off with a .030 overbore....this still leaves room for future growth when the block needs bored again. You are only talking 12 cubes diff between .030 and .080 (545 vs 557).

BOB is looking for a set of OLD iron SCJ heads. Cheap as possible.
