Biulding SC engine for Bonneville salt flats
Hi All, first post here, great forum!
I'm looking at building a full on 3.8 SC engine for fitting into a (under) 260 CI class in Bonneville. I have done some research and as far as I can see the SC engine is certainly the choice to start with given the forged crank and good block.
The car will be a '90 Thunderbird that I have already, nice ride at present if I do say so myself
Without having an engine on the stand in front of me (which I am looking for by the way), I have some rather, umm, unconventional questions:
Another site says that the 3.8 is essentially a 5.0 configuration minus 2 cylinders and some parts interchange. Hmmmm, (lightbulb moment) are the bore spacings and head bolt locations the same between the 3.8 and the 5.0L? How about this; has anybody tried to cut off and weld a set of new tech 5.0 aluminum heads?
How much can I bore the 3.8L SC block and keep the strength. Or, how much closer can I get to my 260CI target?
How much HP will the stock crank and block hold up to? (Given proper ballancing and all the correct prep and oiling work?)
Remember, If I do this I EXPECT to build a radical racing engine, and I have many years of experience doing this. I have just never built a 3.8 engine this way.
