lol ive been saying for a long time that 88mm should be possible on a stock block. lol. The problem at the time was the headgaskets as you would have had to use a 90mm specific headgasket to seal it which on a stock block might not work so great as it will have the firing ring a pretty good distance back from the bore.

Im just surprised it took this long for one or two to get up and running. Its a very simple build and with the extra displacement at really no extra cost, why not? No need to sleeve or any of that.

With everything right these 88mm motors will make 275-280whp.

Everything will need to be TPS based.

Sell me a set of any drop in prototype cam that you understand that makes more power than N1's and I will test them against N1's But I would not buy 184-C since they have been tested here with no luck!!!

If I remember correctly, people did not do these things because they were not sure of the sleeve holding 88 mm. Even though a few N.E guys said it would.
I personally went to a machine shop 9 years ago and the guy said it would not hold a 87.5 mm piston,clearly he was wrong in his personal opinion.
