So in 2002, I had a 225 block built for my 1964 Valiant since the 170 died. I didn't know what I was doing then, but I did ask the guy to bore the engine 0.030" over and he charged me accordingly. I just started my engine breakdown all these years later and, surprise surprise, it's bone stock in there. So now I'm looking for something new to do. I read Doug Dutra's stroker article and that sounds pretty interesting. Anyone tried that? http://www.slantsix.org/articles/stroking/stroking.htm How does that affect the streetability of the engine? For reference, here's what I have so far for the car: 1964 Valiant 2 Door Sedan - 225 out of a 1970s Dodge van - 904 Pushbutton - A/C - Power steering (Saginaw) - large valves (1.70/1.44) from engnbldr, porting job, with 340 valve springs, planed 0.100" off cylinder head - Erson 280 int/270 exh duration cam, 0.465" lift with lifters - Recurved distributor - Double roller timing chaing - Stock oil and fuel pump - 90 Amp Alternator - HEI - Offenhauser 4bbl intake and Edelbrock 500cfm 4bbl with electric choke - Dual Dutra Duals into a Y-pipe and single 2.5" - 8.75 3.23 Sure Grip TBD: - 2600-3000 RPM stall converter I'm also doing some serious suspension upgrades, but the only one I think is even slightly relevant is I'm moving the battery to the back. The car is being built to be quick and handle well on the street. So with that configuration, what would you do with the block itself? Is it worth looking into boring it out still? Doug's article seems to imply not, but I know many people have said they bored theirs 0.060" over and seemed happy with the results. Thanks for the help!
