Hello,
I am a first time poster. I have been researching my build for quite some time and am finally getting things started. Due to budget constraints I can't get everything I'd like or the best but I think I can still meet my Goal of 380 hp and 400 lbs of tq.
Today I picked up a new Eagle 383 externally balanced rotating assembly and a TBI roller block from a guy in town for $500. This kit has the speed pro 12 cc round dished pistons. I dropped of my block at the machine shop to have the prep work done and get it bored .030 over.
The areas I have questions in is with regards to quench/ or lack of, and the intended 64 cc vortec heads. If I had inverted dome pistons that would be great but these are not and my budget only afforded the kit I have. With that can I expect any benefits of an .040 quench/squish with my pistons and the vortec heads? I ask because my compression looks like it is going to be around 10.2 to 1 with .040 quench. If I keep the deck @ .025 and use the standard .040 head gasket I can get my compression down to 9.6 or 9.7 but my quench would be .065. Would this be a recipe for detonation?
I think I want to run the roller lt4 hotcam with 1.6 rockers. 218/228 112 and .525 lift. I know I have to modify the vortec heads for this cam. This won't bleed of much compression but more than an RV cam.
This engine will be going in a 54 f100 and will never see the drag strip, just fun around town and cruising. Thank you very much! This is my first engine build.
