While slick had his motor apart for his cam swap, decided it may be a good idea to work the SR some to try and optimize his combo
11:1 383 AFR 195 head, formerly XFI280 cam going to 220/230 HR

I had 2 days left of vacation so did a mad 2 day thrash on this wasnt sure if it could be done in that time.

Filled close to 3/4 of a coffee can full of shavings not to mention all thats on the floor and god knows where else I couldnt recover.

One day Illl learn to take a decent pic just not into editing or touching pics up- they are the way they are.
Actuallly Im just lazy.
Old (early) Accel piece box stock





Making a mess. Used a very large agressive carbide due to time or lack of
Makes for a pain to pretty it up with rolls but makes headway quick

Its some of the areas you cant see here and especially when you flip it over are hinder the flow on these. Huge step up from a stocker though.

 

Runners are next

Typical porting and approx a 1" siamese just because

Stock
Not fun siamesing and trying to make it look like something.
As some know one port is a touch higher than the other so once that wall is knocked out it takes on a funky look not like a typical figure 8 youd think.


Ill go out on a limb and say siamesing not needed on a 350. Cutting the runner dividers out of the plenum and rounding the diving wall on the runners couldnt hurt though.

Still more cleaning up to do looking a lil rough still

 

Plenum. Better than nothing lol.




Finally adding a little bling. Once upon a time someone attempted to polish it.

Gave it a little love, much better. Not perfect but presentable.
Didnt bother with the flanges just the parts of tubes that show









BTW intake used a 1205 gasket and came in just a touch smaller.

Went back later and pulled the middle hump of the runners down more to blend into the lid better.


Hopefully he picks a little something up from all this.

 

I still wish we could have done the bench test with my AFR 195s. Nice work Ron. One of these days you'll get a shot at my SR.

 

Ron, you seriously do amazing work. Simply another awesome example of your work.

 

Wow, looks great. My 383 had a Crane cam with the same specs. I had Holley heads and had my sr runners extrude honed, but I didn't blend the tops of the runners. I had 10.5 compression and used 1205 gaskets too. My setup ran 11 teens. Yours should also. Keep up the good work. Willie

 

Ron you stick to being lazy about photos if you keep porting like this.

It is seeing stuff like this that gives me that itch to send the XT down to you... I think it'd be a fun one. Just so tired of having the motor apart.

 

Dat's-a-spicy-superram!



Sweet looking work, Ron!

 

Very nice and in such a short time frame to boot. If it was mine I would most likely have left the XFI280 camshaft in it looking at the combination. He has the compression and displacement to tame the camshaft. Let us know if he puts it on a chasis dyno.

 

i may dyno it this time, but if you where aware of my cam install thread on the general side, you will see why I can't re use the cam.

I got the SR home! the work is awesome! and burgers with Ron for dinner wasn't bad either.

 

Sounds I spoke with him once and he was a cool dude. That is a nice SR.

 

 

Nice work Ron !!

 

came out real sweet

 

Very

 

Nice work Ron

 

That looks great Ron........I've come soooo close to sending you one of mine

That siamese should raise the peak a bit......what do you think, 2 or 3 hundred?

 

Thanks for the kinds words guys

Usa'sOnlyWay-I havent forgotten, always up for it! Nice doing something different once in awhile.

ccumber-would have liked to do the test also in order to have real life numbers to back up the work.
Time was a constraint but it was there. Day or two before was told Id need the entire SR assembled not just base/base+runners to be accurate (for him to put his name on it which makes sense). That would have taken some time and Im betting he wasnt up to watching me curse out the SR while trying to put it on there. We all know its a pain

Caboboy-Im not sure how much that would raise the ceiling especially on a monster like yours. What you have shouuuld be amplified in its range just not sure how much farther up to be honest. Some say 100 rpm/inch but who knows yours will want a ton of air period. Be fun to find out!

What Id give to have a sonic tester and go after the SRs last little bit. Holes are no fun btdt

Slick- Very curious to hear your driving impressions as most say the size cam you are going to run is optimum vs the ones that like the 280 perhaps 1989TransAm would like that data too. Always good to compare.
So youve had the stock SR with the 280 both with a stick..and auto
Now the smaller cam with a breathed on SR.
Difference would be nice to see you posting about, where it improved or??
Sure like to know.
Still surprised at how bad that cam got chewed up, post up a pic here.
Looks like a few lobes were on their way out.
Thanks for dinner! Burgers were good despite a waitress who was probably on crack.
