For the better part of a year, I have been fully engaged in the complete tear down and rebuild and performance upgrade of a 1995 GM L-32 3.4L OHV RWD V6 engine. I have been trying to faithfully document all phases of these procedures in digital photographs that I have saved for public consumption on the following image warehouse site:
Hello. I'm posting these pics for others to use as a reference when installing S&S headers. This was done to a 1995 Pontiac Grand Prix.
Test fitting the rear S&S header I noticed that it was resting on the firewall without the dog bones completely installed. So I needed quite a bit of clearance.
I used an airhammer to pound in the firewall. With the dog bones in place I can now rock my engine back and forth and still have .25" clearance at the tighest section on the passenger side of the rear header.
1: Set parking brake and chock the rear wheels. Raise the vehicle and support it securely with jack stands.
2: Crawl under the car, certainly getting greasy dirt in your hair. Get in position where the sensor probably is.
3: Notice, after taking the time to get under the car, that you can't see, let alone reach, the sensor because there's a damn transmission in the way.
4: Get out from under the car and lower it, feeling like a tool the whole time.
The Stock throttle body is only 52mm in diameter. This is hardly enough space to suck in the air this motor needs for peak performance. This unit is 62mm in diameter, and is a much better design than the stock peice. Note that this is NOT a stock throttle body that has been modified, this is a COMPLETELY new peice machined from billet aluminum.
The 3100 and 3400 engines are called Gen 3, because they are the third generation pushrod 60V6 engines. The reason for the swap is simple. Flow and design, both of which the gen 3 triumphs all previous gens. The iron heads don't have splayed valves, D shaped exhaust ports, or in some cases even the larger valves (1.42/1.72). The Gen 2 Aluminum head engines are the most popular to do this swap, but no matter what you start with, the same steps apply.
