Cam lift
 

Hey there, does anyone know how much lift the stock heads can handle? :2:

keep it under .500 lift with a 1.6 rocker and you should be safe. Keep in mind theres no guarantee that they duration is going to be too big.

Puddy the heads just to be safe.

thanx, I think I might just go for some better heads

what are you goals? Set a HP level and make a plan. Decided what you want to obtain and buy the approperiate parts.

How much lift you can run depends on your installed height & clearance to coil bind.

Not exactly sure, I know I want to have some go but how much I haven't decided. It's an 88 lx vert so far 5spd w/4.10 flowmaster American thunder. Summit 1 5/8 long tube headers and bbk shorty h is next on the order list. Just thinking if I should go heads cam intake route or novi 1000, I guess I will have to weigh out the pro's and con's of them both. :5:

And make sure you have a budget for the whole project to be finished right. Too many people want blowers that don't have the necessary funds to put them in place effectively.

Sure the kit may be $4500, but what about the fuel system, igntion, and so on.
Good luck with your build.

Stock long block can handle .512" lift, more if you have the pistons fly-cut to accept more lift, I've run .512" on a stock bottom end before with no problems. If you ask me, I'd go the blower route.

If my cam is 268 @50 will you guarantee it will work with .512 lift?

On the other hand I will bet you I can get a 220 lobe @50 with just over .600" lift to work. It wouldn't be with the stock installed height nor the stock valve spring but realistically if you care about your engine you wouldn't be re-using the stock springs with any cam swap - hell I don't keep them when using the stock cam!

Duration is the more important factor when dealing with piston to valve clearance. Flycutting the stock pistons isn't just for clearing a bigger cam it is also to add radial clearance for the larger valves that come standard on most aftermarket heads these days.

Yeah I had a 93 notch with a 9 psi Paxton on it and it was fun, just thought I might try something else this time. Although it is the easiest way to go, I will probably end up with a basic Novi 1000, full exaust and the gears should be a hoot!!
