I'm looking for and would really like to have an IROC with a 5sp and a 350... Of course they didn't make that so, I was thinking of buying a 305/5sp and put in a 350.

But my question is, could I just transfer all the intake stuff over to the 350?

 

Yes, the intakes are entirely the same. The only difference is the injectors, knock sensor and memcal (chip.)

My friend dropped a 350 into his 5-speed TA and the tranney couldn't handle the power and it blew-up. It could have just been his car it was it kinda crappy shape, someone who frequently posts on this board has a 5-speed 350 and it is very fast. His name escapes me now but maybe he could help.

JR, are you referring to me? There's also Tim Burgess with a 305 5-speed faster than me.

To back up what Ed Maher said, yes, the TPI hardware is identical on a 305 and a 350. The differences are the injectors (19lbs on a 305 and 22lbs on a 350), the knock sensor, the chip, and possibly the EGR valve too. Replacing a 305 with a 350 is pretty much straight foward, there arent any special circumstances you need to know.

About the 5-speed not being able to handle the power, its a matter of luck. Some people's trans have lasted forever, others break right away. I had to replace 2nd and 3rd gear and synchros so far, but I've had no problems with it in the last 6 months.

The only differences are the injectors, calpak & knock sensor. The 305 injectors can be used at a higher fuel pressure on the 350.

Why not instead get a 350 car and put a 6 speed in it. You wont have to worry about a T5 blowing up the first time you get good traction.

Well, because it seems like a general pain in the A$$ to make an automatic car = a manual.... clutch linkage and all (unless there's some kit that I don't know about)

 

there's a tech article on this site. it's not all that complicated.

 

not only differences in chip, injectors, but
the intakes from 85-86 had the early intake
(90 pattern) and the 87-92 (72 degree) had the steeper inner bolt pattern.
