Crap, Im an idiot...

posted in the wrong topic, I got the site and cut it, and hit back a bunch of times and thought i stopped on the right post, but didnt..lol

 

what was that supposed to tell me????

 

Bigger valves are almost always better. But if you are on a budget you are going to be looking at maching expense+the valves+the rest of the junk to hold them down. Since you are on a budget, take the money you'd be spending on the machining and larger valves and get yourself a dremel if you don't already have one. That way you can port and polish the bejesus out of everything you have, TB, runners, base, heads, everything. That'll actually give you a better increase in power than just upping the valve size. Plus it's one more tool to add to your evergrowing collection

 

OK...well I do have a dremel, and I know if I do the porting I'll wish I had a plug in one. Mine is rechargable!!!! So say I don't do anything, but just put this Forged rod and piston setup 76 with the 89 TPI system, what do you think I will get for power, a guestimate???? I know stock I run between 235-245 right. Do you think 300 is possible???

Now since I will have things to sell, 79 heads, and I have a set of 93 350 Truck heads(ported and polished, 3 angled) I would prolly have the money for some machine work after those are sold. And I could port and polish these heads myself(the 89's). Well since I have 1:94/1:50's, would 2:02/1:60's make a difference, will those valve sizes work with the 89 heads???? I have the money for valves right now, its just the machining I would need....thats just getting the valve seat machined for the larger valves??? Like I said I could port and polish the heads, intake, runners, plenum.....what do you think????

 

The porting on your tpi intake won't bolt up. The 89 tpi has 8 holes for the intake instead of 12.

 

What do you mean porting, what are you referring too????

 

The intake ports are different between the older heads and the vortec heads. Hence the intakes are aren't the same.:lala:

 

Bolt holes!!!

 

I also have an 85 intake that will bolt up to the old style heads for tpi. I used vortec heads on my 357 and had to go with the newer style. Let me know.

 

Ummmm......... What the heck are you talking about? Do you realize that he is going with the 89 heads?

 

um....no....
The later TPI intakes have 6 holes per side, or a total of 12. The only difference in them is that the center 4 holes have less of an angle to them, more like up and down instead of at a 90* angle to the intake flange.
