Need advice on TFS 220's Need some advice on running a set of tfs ascast 220's 4" bore on a stock bottom end 346. I got these for cheap so if I have to resale them and get the small bore heads I can.
I dont care to leave some on the table but I dont want to install these and not be happy with just a small bump in power. Car maybe gets out of the garage maybe 5-10 times a year with no track time just a toy. I love the current set up, just looking for more power with about the same characteristics.
If I would run these what can I do to get all I can considering the bigger bore? mill them? bowl blended?
How much power will I be leaving on the table with these?
Current engine setup-
stock bottom end LS1 40xxx miles
228/232 588/595 110+4
42lb Injectors
LS6 Intake
Ported stock TB
SLP Lid
SSRA
ported ls6 oil pump
ls2 chain
PB UDP
