Briggs animal build

[trinik7597]

These are pics of the stock head the other one already had some porting done but I didn't like it and am reworking it .. Figured you wanted pics of stock any how . I will post pics of the other head when done .

The first 4 pics are exhaust port

The next 4 are intake port

That looks sharp

The intake is opened up a bit more on the stock Animal than the Intek head--less of a "D" shape. On my Quas-Animal, I left the exhaust alone and reshaped the intake port into a semi smooth big "D." Since I'm running a coil, I wasn't worried about flow at high rpm, never gonna get that high.

 

[trinik7597]

Yes the intek head had a small D shape !!! I have opened a couple of them up think I have some picks of one I did

Hey Trinik, what cam and springs are you going to run?

 

[ole4]

thank you for the pictures. I once saw a post from MDB where he mentioned that the animal head was not as good as a clone head. Looking at your pictures it looks like the animal head has the runner raised and at less of an angle than a clone, which I think is an advantage, unless I am looking at it wrong.

The anmod1 cam and green stripe duals ..

Hey ole , it is the general consensus that a animal/world formula head will never flow as well as a Honda /clone .. I have read up on the subject a little but can't remember exact flow numbers off the top of my head but they are significantly lower !!! Unless you bump up to the billet head

 

[yalipito]

Is that mikuni a tm28? What fuel will you guys run?

 

[trinik7597]

Yes it is .. Gonna be a Gasser . just 93 octane pump gas unless the owner decides otherwise

 

[ole4]

well if you ever want me to flow one let me know I owe you a few favors.

ole4 or trinik7597, are the briggs intek series heads the same as the animal, but with the smaller valves or they completely different. also is there any advantages with cast iron sleeve engines or are you just carrying dead weight.

Don't know about the heads but I believe all these motor are sleeved anymore .

 

[delray]

david,are you saying the animals are sleeve too.

 

[yalipito]

Inteks are aluminum bore with ball bearing in side cover only.

 

[minikenny]

The intek I just put back together has an iron sleeve. It's like any other model series, depends on the type numbers.

intek IC will have iron sleeve.

 

[trinik7597]

That's right the I/c intek is sleeved and has a bearing block .. The animal block is sleeved as well
