Hi Guys,
Here we go again! I am confused, I have read to much stuff on the internet, read to many dyno flogs, got caught up in the hype.
My Car is a 1983 Cordoba with a low comp 360 in it.
The engine has summit full length headers, performer intake and 600 holley sitting on top with an unknown cam. Rear end is 3.21:1 the rear end is not changing and I am not pulling the engine out again.
This is a list of all my parts I have.
XXX302 heads - Stock rebuilt
1983 318 stock heads used
New 360 valves 1.88/1.6
Mr Gasket .028" head gaskets
New Push Rods
New Lifters
Edelbrock Sure seat 5877 valve springs
Comp Cams XE250 206° / 212° and .432" / .444" on 110LSA
Mopar Performance 228°/231° and .450"/.455" on 110LSA
Double Roller timing chain
RPM Airgap intake manifold
Holley 770 Street Avenger
I want to make my 360 perform, so with my bits I have is it possible to put something together to make my 360 Cordoba have a bit of go in it?
I was thinking to port match the 302 heads and tidy up in behind the valves, fit the 360 valves but have been shot down every which way on that one. Closed heads would get the comp up nice! match with the XE250 cam. But was told will never flow although I have read people who have done it and said it makes 360s go real good!
Then I was thinking after that disaster to go with a bit more aggressive cam, an intake with bigger ports and a bigger carb but problem there is it is still a low comp 360. But it may still make ok power
I don't want to pull the engine out and rebuild it, just want to get the best combo I can with what I have got.
So can anyone see a good combo that would work with any of the parts I have?
Happy New Year
Bruce
