So a mechanic buddy gave me an idea to port and polish the heads and intake....95 cobra comes with the whole gt40 set up and I was planning on doing a tfs stage 1 cam over the winter with tfs springs and pushrods...how much gains do you think I would see with doing the cam AND port and polish the heads and intake?

leave it to someone who nows how to do the job, you can really hurt things if you do it wrong or take of to much material on wrong spots. google tom moss or contact http://www.hunterstyle.com/thumper/, he ports heads also. Both of these guys are very knowledgeable of flow rates and GT40 heads, Mike @ thumper has been porting for many years and give you much better HP number for oyur combo than we can right of teh top of his head. my heads/intake where done by Tom Moss but Mike is very good also. IMHO this isn't just a back yard deal, you can cost your self.

give Mike a call.

I'm sure you'll just tell me to call him but could you give an estimate to how much it would be to port/polish heads and intake? Cause honestly I just recently got interested into doing motor work so I'm still rusty

It has been awhile since mine where done, to get them all done about 1/2 or around there of what a new set of aluminum heads go for or set of used heads ( not including an intake).

This is always the arguement and it is a valid one. do you spend money on your heads or go for better ones. This is a personal choice. gasket matching can be done more or less by you and well net a small gain, yes polishing ( again by a pro, it is more science than many believe) can gain much more tahn just port matching. Tom moss used to have flow #'s on his site ( it is now down) for ported GT40s and they where nice #'s, so yes there are gains to be had but they still fall short of a really good set of aluminums but much better than stock again if you cannot get a good set used you are still inbetween new vs port/polish.

some people like to keep the motor stock or like to stay with irons. IMHO if all you want is a nice snappy street motor, then either keep what have, maybe port match and do the stage 1 cam BUT degree it vs going by the stock timing marks no matter which way you go ( this will also gain you another 8-10hp since the stock timing events can vary alot) and slap in some gears. you posted about adding torque. The stock block is good for about 500-520 crank so a low boost kit would add some also. If you are looking to get the most out of your current heads and intake w/o going aftermarket then sending them out to get polished is what you need to do.

Yeah that's exactly why I would rather just port/polish because I want to keep the original motor the way it is with a bit more juice...so you think the cost would be half as much as a new set of aluminums? Sounds good also I have 3.73 gears in already and do you know of any Lowe boost kits to reccomend with a link? Just so I can get a feel of where to start if I decide to go that way later on

My vote for a supercharger would be a vortech

another option is the kenne belle

I'm a vortech fan but to each thier own.

If turbos are more your flavor this is the best place to learn more and get the best fit and info:

just remember the block has the limit then it wants to come apart, if you feel you want more boost or more out of it then look into a better block like a dart, world or boss. If you know the limits then you will be good.

If you want more hp N/A then a bigger cam, better heads/intake and stroker kit will help. ( all in future speak of course )

What about this s/c: http://americanhighperformance.biz/1...4FA218-010.htm
And would it even fit? I don't see why not since there the same motor as mine

skunk21

same motor to a point but different accessories/brackets, etc. call vortech tech and ask is what I would do but doubt it will work.
