Well I hope this doesnt post a dozen times. I dont believe any difference in power between the two engines you mentioned will even be noticable. I wouldnt push it more than 10/1 on the compression...

Well now, this gives me ideas for a winter project. I have 2 MK IV blocks sitting in the garage. I have a lot of pistons and rods. I have a couple sets of heads. (and another set coming at the end...

Pat, now Im curious....what other mods did the Mk IV block require to take a 3/8" stroker crank? I thought about doing that, but too many people told me it was a real pain to prep the block. Bottom...

Yep, it's your fault Pat! You drove off another one:LOL: You just have too much knowledge about these things. Try to contain yourself:p Yes, I agree that we need to hear from Dusty to see...

Ya know Eric, maybe we DID scare him off!:eek: Dusty!! Where are you ????

No, not a disagreement Eric, just a difference of opinion.:D I have nothing against aluminum heads at all, but Im trying to keep Dusty's expenditures to a minimum...it's going to cost enough as it...

Pat, I dont know what heads, that's why I asked him to post the casting numbers. I agree, if they are the small ports, no way will they work. If they are large oval ports, the with a little work...

Post the casting numbers on the heads....they might be fine to use with a little work. The peanut ports were not used on all truck engines. Might as well save money where you can. A roller cam...
