It's all in my signature. I have a 9.5" converter from Tri Shield Performance I'll be installing shortly. It is 11 lbs. lighter than my current converter. We will see how that feels in the Spring.
That's cool I got sick of the huge cam drivability issues with the chevy stuff I had before . I would much prefer more low end and something more street friendly. Any suggestions on where to do more work on the heads would be great nice build
From what I've heard, bowl work alone on these heads brings them up 20-30 cfm numbers, so that would be a great place to start with a valve job
I would start another thread and ask about who does porting. I know Jim Weise (Tri Shield Performance) can probably get your iron heads ported. It will not be cheap though. With the advent of aluminum heads, it really pays to start with them in the first place. Out of the box, they will outflow most if not all of the best ported iron heads. http://www.v8buick.com/index.php?members/jim-weise.11/ http://www.trishieldperformance.com/
Well I started all the port work have 4 more ports to go just wondering if there were any special places other than the normal stuff like bowl pushrod pinch what not. So yep I think I will start a new thread and see what comes up thanks
Larry where did you get that calculator it looks way more accurate then the one I found on line . And sorry it was asked earlier in this thread my name is Justin and I live in jenison mi
I am a auto mechanic at America's auto auction and build lots of new hemi and ford 5.4 engins along with some gm 6 speed front wheel drive asin transmission. Along with lots of electric Diag
Justin, the calculator is at the end of this article on Dynamic Compression, http://www.empirenet.com/pkelley2/DynamicCR.html I keep it on my desktop. It is very easy to use. Some guys seem to have a problem downloading it. It was easy for me, on Windows 7 and now 10. If you look at the snips I posted, you'll see 3 headings up top, one for each calculator. From right to left, Compression Ratio Calculator, Cam Timing and Overlap Calculator, and Dynamic Stroke Calculator. Start by clicking on Compression Ratio Calculator. Fill it out and click calculate. Then click on the Cam Timing Calculator. Use ADVERTISED duration, not .050. Fill out the Lobe Separation and Intake Lobe Centerline, click calculate. Then the last calculator is the Dynamic Stroke Calculator. Crank stroke for the BBB is 3.9, Rod length is 6.6. Click calculate and you'll see the Dynamic stroke. Go back to the Compression Ratio Calculator. Next to the stroke is a small white box. Click on that box, and you will see the Dynamic Stroke Length substituted for the Stroke. Click calculate and you will see the Dynamic Compression Ratio. Let me know how you make out.
It loaded fine I will know much more in the coming weeks with actual measurement of the short block and after the heads get decked and use it thanks
Larry I have to say the first post was awesome about all the oil mods and such. Have Ben looking through this forum and was wondering could I get my goals of high 12's with a stock looking 455. Manifold and all , or is my smog intake to horrible to make that much power . I just think it would be cool to look like a stock engine and run hard
When people port the intake do thay usually drop the 4 hole divider and make it as close to the edelbrock plenum as possible . And what about the exhaust manifold .... acid porting like old super stock stuff? Just seems like to much fun to have something that looks factory and runs strong
if you paint an aftermarket intake red it's pretty close to stk for those that dont know, especially if its a dual plane. I painted the offy 360 single plane on my brother 68 gs 400 looks stylish besides the fact it's a single plane. in 97 when I first started racing with a totally bone stk 455with 3.08 gear and m&h tires it went 13.90s. just a gear change to 4.10 it went 13.20s. small cam and carb I was in the 12s
Nice it seems the buick 455 runs much harder than I thought and it's kinda cool that it's not the mainstream chevy ford mopar stuff iam used to
As of now iam verry much considering a stock appearing gs as the car this goes in it would be to much fun at test and tune haha
