Okay everyone, so mid summer last year, i blew my bottem end up in the cobra and am finally getting around to fixing it. I went to a machine/performance shop for the first time today (best of the best around here), after searching everywhere i could think of for forged shortblocks, and talked to the owner about a complete rebuild. So he asks what if i want it for a supercharger or N/A and i tell him it will be supercharged just not for some time (anywhere from 5k - 15kmiles down the road). He tells me that it is not a good idea at all, because of the compression being low, and that it is going to be sluggish and a 'pig' as he put it. Now i could understand losing some power, but is it actually harmful for a N/A engine to run on low compression (prob around 9.0-1)?? He made it very clear that i should not drive the car until it is supercharged and even told me he would rather build something with a higher compression ratio and see me spray it, which im not really that into (although the thought of a stroker kit is intruiging). I have the funds for the build, but not the charger right now, and really only want to have to fix this problem once, so all advice is appriciated. Thanks guys, hope to be back on the roadd soon!!
