Re: Mating Two V8's, ( Freight Train) vs. Harmonics

Phasing, go for sound, if you want a V16 even as it can be fire, couple it at 45 degrees, if you want the sound of two V8's in unison couple at zero degree. On the PowerNation Horsepower show where they coupled two 600 hp Big Block Chevys, they said it was easier on the starter, and it spun over a ...

Re: 8.7 deck sbf, Whats the biggest stroke possible?

8.7" is generally used as an alternative to the 8.2" for building 363-385 engines and maintaining a decent rod length.
Guys wanting max cubes will go with a 9.5" deck.

Re: Hit Water. Can this be fixed?

Found this pic I took a long time ago when repairing a 289 head that cracked. A thin spot in the bowl cracked, so I drilled a hole between the valves, cleaned the spot really well from the WATER JACKET side of the crack (as well as the port side) and added a thin layer of JB Weld on both sides of sa...

Re: Mating Two V8's, ( Freight Train) vs. Harmonics

PowerNation did a test where they linked two Big Block Chevys together and dyno'd them. I believe they tried two different ways of linking them... one in synch, the other 45 degrees, maybe? Going by memory, but here it is. Linking them together starts around 29 minutes into the video. Beginning is b...

Re: Lube for valve stems?

Permatex Ultra Slick Have been using it on everything. Super thick, sticky liquid. Will not use a paste of any kind, as they turn into a solid over time, and gum up if an engine is going to sit for a long period of time. Lubriplate and even Redline assembly lube that comes in the little tubs are gui...

Re: 289 Build Help

Comparing what was fast 20 years ago... and what is fast now is sort of irrelevant. He just wants to be able to keep up and possibly outrun the kids he hangs out with! lol They don't have super fast cars, but they are faster than his. :) An engine burns air/fuel. The more air/fuel you can burn, the ...

Re: Bad Valve Stems?

Are you sure the valves are not STRETCHING... which would thin them out in the middle?

Re: 289 Build Help

Choice 1 Remain slow, but not quite as slow. Keep the LONG RUNNER intake, and cam accordingly with a hydraulic roller around 220 @ 0.050" on the intake. May as well keep the 3.50 gear. Won't be much faster. Will run like a lightly modded original Fox body mustang from back in the day. (pretty much w...

Re: 8.2 Deck Dart/World Windsor longest stroke possible?

Question for you Gents as reading this got me wondering. How low can you go with rod ratio? Some of these combos mentioned would equal a ration in the 1.4's. WIll something like that last for street driving? Or drag only? This is why the 8.7" deck blocks were invented. They look pretty much like a ...

Re: 8.2 Deck Dart/World Windsor longest stroke possible?

New Boss 302 blocks are the ones with the short cylinders.
Many go with the 8.7" blocks, which are a great way to open up some room, as well as get some decent rod length.

n2omike and 289nate, I have to ask, what is your actual rear gear, what diameter tire are you using and what is your trap speed?

Re: 289 Build Help

The GT-40 intake CAN help a 289-302 make OVER 400 hp, and has been done many times. The intake has to be ported by someone who knows how to flow test each port, and the upper plenum matched to the manifold. The throttle body can be opened up to 75MM without losing gasket seal. I always port the Gt-...

Re: Hit Water. Can this be fixed?

I had a bowl crack on a 289 head where it was super thin. I drilled a hole through the head under the valve cover into the water jacket... cleaned it really well and used JB Weld on the WATER JACKET side of the crack to repair it. Used it for close to 10 years after that. Never an issue. Tapped the ...

Re: 289 Build Help

Cam....I'm leaning to the solid flat tappet with the EDM hole in the lifter. Specs are where I'm stymied a bit, and I've hesitated to ask this because Mike is the expert. But I'm curious and the answer may help others. The cam specs you all are calling out are much more aggressive than the one Mike...

Re: 289 heads on a '84 302 block?

289 has steam holes at 12 O-clock right above the cylinder. On 302's they moved them off to the side a bit. A head gasket can be used as a template to either drill the head or block so the steam holes between said block and head match up.
