Planning while I save, engine mods.
So I've started planning the next stages of my upgrade and quest for more power without tearing apart the shortblock.
Next time I have enough money to do any kind of major work on it I'd like to get a bunch done at once.
So here are a few questions before I get all involved in planning out how much this is going to cost:
I currently have 64cc heads and 18cc dished pistons in a 355 for a SCR of 9:1. If I were to change to smaller CC'd heads, do you think I'd have an issue with valve clearance? (Not that I wouldn't clay it regardless of what I thought clearance would be.)
Should I stick with a carb or stick FI on it? If I were to go the FI route I'd probably put TPI on it as I'm familiar with tuning "stock" PROMs.
The ever present cam question:
I'd like grunt from idle to about 6000RPM, of course I'm willing to make a few sacrifices on either side of those marks, but if I were to go with TPI then it would probably behoove me to keep the power down low (since that's where the GM TPI likes to make power). The biggest issue is with the LSA - is 110 streetable enough to daily drive?
Thanks in advance.
