Fiat SOHC Performance Tuning. 1. Introduction. Despite having very humble origins as a power-plant for the 1969 front drive revolution Fiat 128, in my opinion the SOHC is quite a spectacular engine and Aurelio Lampredi's finest mass produced work. Notwithstanding it's 'inferior' design non...

Found I have a bent valve and would like to get a direct replacement. I believe it is a Nissan valve from a 240 or 260 but anyone's guess. One of those final stages of machining a 15deg back cut and "oh and by the way" deals.

TIA

For those that like the challenge it is possible to repair the fuel tank sender resistor by rewinding it. From ebay I located 30' of 38 guage Nichrome wire. Resistance is 43 ohms per foot. You need about 10 feet. $5 for 30 feet of wire. First step with the sender removed is to pry up on the...

I guess it has been a while. In fact I may be fuzzy on the procedure, it's been so long. Can someone remind me of the pit falls of timing belt and tensioner replacement. The manuals are vague on critical points as I recall.

Hey all, in my white '83 X, I have a newly rebuilt 1500 slightly modded with milled head (.070), adj. camwheel, PBS SX-1 cam and homemade header/exaust with open cone type air filter. It runs really good, better than I expected in fact. I got a spare AFM sitting around and was wondering if there...
