Hi Guys,
Well if you have been following me then you will know I have been playing around with a 360 into my Cordoba. Its taking me a while to realize that the low comp 360 is really a lemon. Doesn't matter what you do if you don't have comp you have a lemon!
My friend in Aussie and I have devised an evil against the grain plan to get the comp up. You guys will probably laugh at this but its worth a try!
I have bought some 318 heads, I am going to have them milled 20 thou, hope to get them at 60cc or below, (260 heads approx. 72cc) going to have the 360 1.88 intake valves installed, square up the intake ports and port match and blend the throats, this should get the comp up to at least 9.3:1
Now before you cry you are killing your air flow, yeah I agree with you! But and here it is, if you can turn the 360 to 4500rpm with 318 heads then it will go like a rocket, sure it won't make as much HP but I don't drive at 5000rpm all day, I want blistering 0-60mph times not top end of 200mph! or 1/4 miles times in the 13.Xs
The air speed with the small ports will be incredible, the off line performance should be tire frying! The compression will be up so the cam will bark into life. The thing should take off well with tire frying performance!
I am going to give up fast 1/4mile times for tire frying 0-60mph times, as this is where most of my driving is done on the street.
I have the heads in my garage, going to start the port work soon.
Anyone got any good advice or done what I am doing?
See You
Bruce
