Unforgiven
solid fixture here in the forum
I have an open question for you all...
First .. the question..then the reasoning.
The question is.... should I de-tune the race motor I had built... or, should I lower the compression with new pistons to turn this motor
into a nice dependable street car motor.
The reasoning is..... I am going to be fading out of the race truck scene in a couple years do to the fact that it is taking a toll on my body.
The wife would like for me to build her a 1966 chevelle (like she had when we were in high school).
I was thinking that if I could find a car for around $15 - $20,000 .... I could finish it in a short amount of time, and put my race motor into it.
I have to buy new pistons anyway , so ... What I have in there now are 11.5 : 1 flat tops. And the blower pushing up to 12 lbs of boost.
I was thinking about lower the pistons to 10 : 1 , and lowering the boost so I might be able to run the pump E-85 fuel.
So we dont have to search back through my thread.. I will refresh on what I have now.
383 SBC Bow Tie Race Block
Forged Scat Rotating assy. Balanced to 0.02 gram ( 11.5 : 1 static compression)
Promax 200 Aluminum Heads (2.02 valves) (1,6 roller rockers)
177 Weiand Blower ( manifold ported extensively) plus ( multiple upper and lower pully combo's)
Holly Super Sniper EFI
Hyperspark ignition
Howards Cam 243/253 @ 0.05 dur .507/.530 lift (1.5 rocker ratio) 112 LSA
1- 7/8 headers.
This motor has alot of torque... So I think I can afford to lose some for the drivability factor on the street.
My wife would drive this car to work daily, and we would like to play on saturday night.
Don't need a drag car... just a better than average saturday night special ( if you will).
This is all in the idea stage at the moment...but it is the goal.
I do not plan on pulling down the engine (melted pistons) until around JANUARY because of this messed up year we are all dealing with.
So at the moment... no pics. Just talk.
Below is a pic of someone else's car... but it is a pic the wife sent me , to show what she would like..
I sent her back a pic of what she could expect below ( again, not our car)
So what are your opinions :
Should I keep the motor the same and just write another tune...
Or should I lower compression and change the cam profile, which would lower hp/ tq all together.
Would like to hear the reasoning behind your opinions..
