Ouch! Did/does it have a stock crank? Is there an aftermarket forged crank for the block? From my understanding, the block can be drilled such that it will support 4 bolt mains.
Interesting, I was talking about putting a girdle on my 3.8L block and one of the vendors on here said you'd be better off with a forged crank. At least for the 3.8L and 4.1L block, the forged cranks have came down in price quite a bit.
What turbo are you running? Do you have the stock intercooler setup or an aftermarket air to air IC?
Have you considered a chevy bowtie or are they too expensive or are your goals something else? As in getting the most out of the stock block?[/QUOTE
Our (RPS) crankshaft distributor is currently working on developing and producing a forged crankshaft for the 4.3 Sy/Ty blocks. There are a few things in the air at the moment, but the cost will be anywhere from $550-$1,200 I think.
Considering that other aftermarket Sy/Ty crankshafts
START at $2,500 or so, do you think there would be much interest for a Sy/Ty forged crankshaft that costs up to $1,200? (Of course assuming that the design was good and it was a strong piece...)
What vendor told you that a crank is better than a girdle?
My buddy has Bison tune his car to about 520rwhp , and ran 10.3's with it. It was a 109 block, girdled (although I would say billet mains instead), stock crank, stock rods, and JE pistons I believe. My point is that with billet mains or a girdle it will help hold the crank in and help stop the flex. Although the forged crank is still much stronger, the center mains are still not very strong. I am saying all this in reference to an engine not making more than 650-700fwhp. This has been the experience of our local club member's engines with girdles vs caps vs aftermarket cranks.
Stock crank, good crank alot of money. All billet main caps. Stock/modded intercooler have an air to air not sure if I want to install it. 64/66 Gen 2 PTE Turbo with a buick flange and downpipe/external gate. Thinking about using turbo on my Buick and detune truck as it is a real PITA to work on.

My crank distributor recently told me that he is looking into having some Sy/Ty cranks made. Apparently there are a few things in the air at the moment which drastically affect the price, so he was telling me that they would be anywhere from $550-$1,200 a crank.
Just a heads up.
