I finally got done with my head and intake swap. I ripped off the ol swirl ports and went with a pair of 305TPI heads (181s i think) that were ported and polished with new Z 28 springs and a new polished RPM air gap to go with that. When i first removed the heads i finally got to see the dreded swirl port heads, it was worse than i thought when i looked in the intake with the valves off. The car pulls much better into the top end but it still needs a lil bit of tunning. I have the holley 670 unit but i have not put it on yet do you all think I need it or is it over kill for what i have
If i put on the holley unit I will not be able to run the NOS plate becuase of the holley 2" bore. Can i enlarge the Nos tbi plate to 2 "?

Hey Zrated that looks really good man. I am still contemplating what manifold to get for my combo too. Do you still have the stock RS hood? If so how tall is that adapter plate and what kind of air cleaner are you using to make it fit and how much clearance do you still have?

 

I was trying to post more pics of the swirl ports earlier but it did not work

 

I have the SS hood and it fits very nicely under the hood the whole set up is about 2" taller than stock so it will not fit under a stock hood

 

Ok that makes sense that you have the SS hood; that's too bad I was really hoping you still had a stock hood and it would fit by some phenomenon, but it was just wishful dreaming I guess an air gap and a tbi adapter wouldn't fit under a stock hood.

 

about the nos plate all you need to do is order one for a 454 tb it has the 2 inch bores

 

Your 187 castings look a little rough from that pic. How many miles did they have?

 

they had about 140k and yea they do look kinda rough

 

How much does the plate cost and where can I order it from?

 

You got some bling-bling goin' on with that engine compartment.
