Biggest reliability issues with T-bird? Reply #16 – May 02, 2009, 12:25:27 PM Quote from: Grumbles;270152Will an HO cam work with SO firing order? If I'm reading my chilton's correctly, they're different orders.If you install the H.O cam,you'll need to install the H.O computer,19# injectors,and wire it like a 351W (plug wires).it would really help to upgrade the exhaust and intake at that time as well.

Biggest reliability issues with T-bird? Reply #18 – May 02, 2009, 04:29:39 PM Years and years of leakage left the underside of the vehicle a nasty hazardous mess. I bought a pump sprayer and purple power and took the car to the local car wash equipped with jack and jack stands. Degreased the undercarriage and put $6 worth of car washes to it. World of difference now. I have most of the leaks fixed minus the rear main seal. I haven't decided whether to find another short block to put my GT40 heads on or just build the top end till she blows up. Quote Selected
Biggest reliability issues with T-bird? Reply #19 – May 02, 2009, 08:43:02 PM Going carbed, no computer necessary. A little confused though, if the timing is different, wouldn't the crank have to be different too? Quote Selected

Biggest reliability issues with T-bird? Reply #21 – May 03, 2009, 08:33:26 PM I guess what I mean is, if there is a timing change, wouldn't that then mean that the pistons are in a different position? Quote Selected
Biggest reliability issues with T-bird? Reply #22 – May 03, 2009, 08:57:08 PM No, because in going to HO, the cam itself is changed, but the timing isn't directly affected by the bigger cam, just the firing order is different. Seems as if logic would make this impossible, but it is possible. The cranks between HO and SO are identical.On a related note, you can do what's sometimes called a "mid HO" conversion, using the HO upper/lower throttle body, etc...But, if you are going to use the 19# injectors, you MUST ALSO use the HO cam and an HO EEC...those three components have to be used together!!

Biggest reliability issues with T-bird? Reply #24 – May 04, 2009, 06:35:09 PM well if you put the engine at top dead center. Pull the #3 plug. Rotate the engine manually at the crank. If the next firing cylinder is #3 a burst of air will push past your finger. That is a 351w/302H0 firing order. If air didn't push past then the next cylinder to fire was #5 standard 302 order Quote Selected
Biggest reliability issues with T-bird? Reply #25 – May 08, 2009, 12:43:00 PM I have pressure washed plenty of vehicles. I start the engine when it is cold , leave it running ( with the emergency brake on) and have at it. I stay away from a direct spray at electronic stuff. If the engine dies, I dry out the inside of the distributor cap and re-start it and continue. That's is how I do it but I am not advising anyone to do it.;)t Quote Selected
