If you had a stock 260 engine and you fancied warming up it's performance without spending a fortune, how would you go about doing it?
Let's suppose that it was going to have a rebuild so it is going to be in bits anyway.
Thanks.
There are more options than we could all list here (ask Duke & Buck). Built more than a few from mild to ridiculous. Keep in mind that each thing you change only moves the weak link along the chain.
When I got my Tiger it had a dual point dist. low rise Tiger
manifold 4 barrel carb, Stock exhaust manifolds. Heads,
manifold were port matched and exhaust was cleaned up.
No problem with early Corvettes and 80's Mustangs. I have
64 heads with 184/160 valves that I'm porting to same specs
Worked great for me could send what specs I have,
Clean up portsband chambers in head, larger valves, threaded rocker studs instead of the push ons, and add a can.
I had the 289 heads on my MK1a I had driven several cars. The difference is pretty decent. The period correct Edelbrock F4b can still found for 100 to 200 bucks if you shop Mustang guys, put Tiger next to it and its 300 to 350...
Convert your close ratio gearbox to a wide ratio setup and put in a 2.90 first gear. That's a 25% lower first gear for better off the line performance, while keeping the stock 2.88 rearend ratio for highway cruise. New wide ratio gears will cost you ~$450 and you can sell the old close gears (assuming they are in good used condition) for ~$200-$250 on ebay.
IMHO it's the best bang for the buck.

Why does it feel like an overdrive when it still has the same 1:1 4th gear?At cruise, it feels like an overdrive.

I agree that trying to get any performance out of the 260 is not the best option. My 260 ran great when pulled. It looks awesome as a OEM restored display engine. Still hunting parts for it.
Going from 156 RWHP to 386 RWHP is the best option.
