got a 1985 carbureted engine, d15a1 I plan on building for dirt oval racing, going to bore it 0.40 and was wondering if the d15b rods will work out of the vtec engine being that their 1.37 on my stock crankshaft before starting all of this massive work, I do intend on using the d15a1 cylinder head 12 valve. its been shaved 0.45 thousands and had a three angle valve job, I was going to use the SI cam from a 1985 crx as well. Just trying to make some power, Any help-information will be greatly appreciated. our rules require us to stick with the carburetor set up.
