That Penrite oil I am using was ordered from Summit Racing.  They sent me their catalog a week ago and went through it page by page.  I can see why you are going to a small block Chevy.  There is so much available and it is ready made at very affordable prices - compared to bike stuff.

Have a Merry Christmas

I don't really want to be right on the class limit with the 4" bore. if we (Goggles) break it and I have to rebore , it could be a problem

Grummy, I think you're being overly cautious.  Let's follow that scenario to its logical conclusion.

We're talking about a Chevy V6 block.  They're as common as dirt, and you can likely pick one up for scrap value.  

If it breaks in a way that's going to require a rebore, something else probably went wrong.  Cheating yourself on cubic inches to keep the option of reboring a disposable block - likely the cheapest component in the entire build?

Reverse the thought process.  Take the horsepower increase the additional capacity gives you and divide it by the cost of a spare block.

Where are you going to find cheaper horsepower than in that equation?  :roll:

And that cash outlay would only be required if, indeed, it did break.

We are NOT rebuilding . . . We are reloading.

Yep. Scrap value on your side of the planet.
I'm in the country where buying a small can of coke
in a gas station will set you back $3.00
A Chev v6 will set me back about $2500.00
If I go for a crank that uses a stroke that's used in a V8, the rest "should" be
easy, especially on the wallet. And I'm not talking 3.48".
I'm trying to keep it well inside E/Gas
Of course , if I could find something like Stainless ran in that big car
That would be easier

Sorry , what...

I'm liking the Chevy because of the availability of hi performance parts.
and with the four inch bore we can move on from the 1.7/1.5 valves
3.25 inch stroke would also work and I would be fine with that

Why not just build a V8 and run just 6 of the cylinders. Keith Dorton has built several of these and they make great hp and there are a lot more parts for the V8 than there are for a V6. There is a Monza that runs at the salt by one of the Burkdal family that does this and it is running close to the record in the E class and pretty much with "Ebay" parts.

6 cylinders of a 4.125 bore with a 3.25 stroke would get you right at the 260 number.
Just another thought.

Rex, you've mistaken a teacup for your spirit measure again. If we could just pop a V8 in it, we would, and we'd destroke it.

Our car is a little bit shorter than my attention span, if we had a small block in it it'd be fuller than the confessional on New Years day.

If a V8 would fit. I would use one, although a chev, without the water pump may go in
If we moved the gearbox back an inch or two, shortened the tailshaft to just a yoke with a uni joint on it
cut the water tank and moved the battery

And my Dad keeps reminding me that I have a 253 ci holden V8 sitting at his farm

However, there just isn't the room

I see now! It is the 10 lbs of $hit in a 5 lb box problem! Going with the V6 thinking have you ever considered the Ford/Yamaha V6. I think DOHC with 5 valves per cyl. Tracer Racing used one of these to set the E lakester record a few years ago.

The Chevrolet "small block" , 90 degree,based V6 is probably the best way to go, we ran a similar sized one with a set of hair dryers in our Lola T600 when I was at Interscope Racing. Ryan Falconer built them, used Porsche Kuglefisher injection from a 935 turbo and made about 900 hp, so the potential is there. We had some Chevrolet aluminum heads that were small block based and when we tried the V6 at Indy we had the splayed valve, big block style head. Those engines were making about 800 -850 at 9500 with 56 inches of boost on alky. I think that they were about 200 inches. ( May have been 160 inches, don't really remember)
