As it is my first engine build, thought I would share my thinking and gain others input.
My engine was leaking oil and coolant, so I decided to tear it down, replace the seals, and repaint for a fresher looking engine bay (pics of starting point to come). The engine is starting as what I believe to be a stock 998 with a HS4 single carb and pancake filter. As with most projects, I hit the slippery slope and started debating engine upgrading. I currently have a 12G202 head laying around (got in the purchase of the car) and what I believe to be a pressed steel exhaust for a mini (see attached. may be for a b series). My buddy happens to have a 266 cam laying around.
So the final plan would be to have:
FDR: See below in questions
Stock block and crank
12G202 head skimmed for 10:1 CR and ported
HS4 with stock intake (cut from exhaust)
Pressed Steel Exhaust
- Will the upgrades give me enough power to drop to a FDR of 3.1:1? Would love to get some higher top end speed as here in Michigan there is a lot of highway driving.
- Is the HS4 big enough? i also have twin HS2s I could switch to but I like the simplicity of single carb.
- Will I need the Aldon Yellow Dizzy? i have seen most people upgrading convert to these.
- Any experience with the pressed steel exhaust? or should I got for LCB?
I do have the Vizard book and reading as I go along.
