I currently have a 2056 with a great top half. Big valve heads, Micro Squirt, and 96mm P/Cs. But I want more HP. I have set myself a $4K budget for building the bottom half, potentially going to 2.3 with a stroker crank, adding cam, balancing, and making some valve train improvements. But I started thinking, you know how dangerous that is, are there any other engine options in the $4K range that would provide reasonable HP increase. Not looking for 250 HP but just enough to keep it interesting.
Anyone got thoughts or suggestions? Open to most options but not sure that converting to water cooled is even remotely possible with the budget limit. Engine swap for proven HP increase seems the easiest option but thought I would see what the brain trust could come up with. |

The Scat C-25 and C-35 are carb cam designs from the late 70's, on a 2056 a C-25 doesn't give you any more performance than a stock D-jet IMHO.
On a stroker engine my favorite is the WEB 163/86a, hair lumpy,good idle and gobs of torque, but still drivable for busy highways. Con is you need to run dual springs and manton pushrods and it has poor vacuum signal for ITB fuel injection. Can be worked around and IMO worth it. For a bit better vacuum maybe try the Web 494, but all ITB intakes suffer from poor vacuum signal with cams that have greater than stock durations. Note, I can't remember if a 494 is a reduced base circle cam, a stroker you have to have this because one lobe will interfere with the rod. |
