[QUOTE="skaarew04SVT, post: 10698528, member: 65296"] So today I had a very interesting 25 min convo with John Tymensky @ Modular Performance. Very nice guy.....and took the time to actually talk with me. I asked him about the limitations of my aluminator, the strength of the block, the pros and cons basically. He is a firm believer in running 10:1 compression when running e85, even in boosted applications. Also had very good conversation on the expected manley hbeam rod longevity. John def recommended the Oliver Ibeam upgrade, lighter weight and much stronger than any power i will ever throw at it. He quite frankly said I am asking the stock manleys to perform well beyond what they are conservatively rated for.....although he did confirm that there are people pushing them well beyond there design envelope successfully, as we all know. Excellent convo on cam choices as well! Long story short, I have narrowed the options down to 3 or 4 scenarios. Still have to add up cost and of each of the following scenarios. Car will be down for a while....it might be 6 months to a year, I really don't know. Gotta get the gameplan rolling. Here are the options that I am considering, in order from most affordable to most expensive: All options include the same headwork, really comes down to the shortblock options. I am not going aggressive on cams. [B][COLOR="Red"]1[/COLOR][/B]. Stage 2 MHS heads, cams TBD. Keep 10:1 aluminator shortblock as is, dont touch a thing. [B][COLOR="red"]2[/COLOR][/B]. Stage 2 MHS heads, cams TBD. Crack open shortblock, re-use stock crank, upgrade to billet Ibeams and a 10:1 ish Diamond piston with Valve reliefs. I am sure there would be machining work required, polishing of crank, etc etc. The block should be plenty strong for the power I am looking to achieve. - This scenario assumes I do the build myself, however, I would feel better letting the pros do it.

Boss 5.0 block built by John, same internals as mentioned in option 2. I would do the longblock assy myself. Head gaskets are included with the longblock from Modular Performance.

I would send him my MHS heads and cams, and he would assemble the whole longblock, degree the cams, etc etc. I will be posing these scenarios to him in an email later, and will be discussing options with him as the gameplan continues to be formed in my head.
