Big Power!!!! Help

[chicane67]

Stuffing a big block into a first gen is nothing new. In fact, its quite simple and is done quite often. The header fitment is the most common challenge, but Stahl headers took care of that 35+ years ago. Hooker also makes a decent set........ and Lemons headers..... and..... its not that hard at all. Id do a 502. Making it run is no different that the requirements of a small block. They all need fuel, air and spark.....

200-220 would be fine. But at 0.060 over, I dont think your gonna be there..... it really depends on the core shift..... but youll probably see numbers in the 190-195 range, which isnt too bad and I could live with that but wouldnt boost it too hard. Id step up to a better block, more like a bowtie at a minimum or even a Motown. It doesnt add too much to the final parts bill, but from that point, you can boost it all you want and beat the hell out of it...... with it laughing all the way.

Chicane, won't I need to change the front end ie suspension to hold the extra weight? What about the crossmember? I think I would also have to change the driveline, and obviously upgrade the rear suspension.. Would you agree with all of this?
My 69 camaro x-11 is all original no mods or upgrades ever except for rear traction control. Again thanks for all your help. Paul

If you build the small block your talking about....... your gonna need to replace all of that anyway at that power level. Small block or not, 500hp is 500hp and it will twist things up just the same...... with a slight advantage going toward the big block because of its natural torque production.

Front springs at a minimum, yes.
Cross member, maybe.... maybe not, depends on the transmission you are going to use.

Thanks chicane, I was really hoping to avoid having to change all of that right now, but it is very easy to see that when you start building a pro touring car you need to do it right the first time. I really was hoping just to build an engine but it seems I just need to start the whole project and do it right.. I guess paint and body should be first.. then chassis and suspension and then motor and interior. Well I was thinking I was only a month out from back on the road maybe now it will be at least a year..
Thanks Paul.

I disagree . if you whant to go realy fast and take fast corners and have high end speed . build yourself a 383 stroker . i just orderd one for my frind a 500/525 hp 500 lbs feet torque .73, 350 4 bold 30 over eagle stroker kit dart heads ported heavely comp cam xe 274(flat tapt cam) roller lifters roller rokkers ecetera ecetera . 6500/6700 rpm wil give you more high end speed over a big block the weight diferends makes you stop faster and able to break longer, it also corners mutchs faster . and 500 lbs feet of torque is plenty!!!!! forgive my spelling ....

CHECK OUT MY CAR UNDER THE VBGARAGE UNDER PROJECT JUST-N-SANE!

You will never get 575 hp out of a 350 without being very expensive and very radical.. unless you use a blower.. then you are talking about $8000 to put it all together!

Thanks for all of the help from everbody. You guys are the greatest and have given me enough to think about it.... I think i will probably sell my 350 block or let it be a nice piece that looks pretty in the garage.... Everyone needs to have a engine just sitting around.. So instead of project Big Power lets go to Project Big Block Swap..
Please see new Thread... Thanks Paul
