I have been doing a lot of research trying to figure out some of the requirements for this engine. So far I have purchased a set of Trick flow heads, chamber originally 61cc and milled .015" to make it 58cc, they have Andrson hi rev valve springs, stage 3 port and polish. A set of 7/16" 1.6 ratio Trick flow roller rockers, ARP rocker arm studs, a set of Trick flow hardened pushrods, 70mm BBK throttle body, 70mm BBK spacer, Trick flow track heat upper and lower intake, 3/4" or 1" Trickflow spacer, FRPP 24# injectors, 70mm cobra MAF, Accufab FPR and a stock 88 GT roller block in great condition. My question is what internals would do me best, I'm looking for a great street/occaionally strip car, 375-425 hp with a 93 LX convertible 5 speed with longtube headers, BBK H-pipe no cats, BBK CAI, FRPP 3.55 gears, Steeda Tri-ax shifter, Steeda subframe connectors, UPR upper and lower control arms with new bushings, Tokico Illumina shocks and struts, I think that's it. The next items I want to purchase are the crank, connecting rods, pistons, bearings and the cam, that way I can go ahead and have it bored and internally balanced at the same time. I want to keep the compression low enough to one day add a supercharger. Thanks in advance for your time and insight.

Stock rods, stock crank, stock pistons.

Done.

Well your not internally balancing a cast crank anytime son unless you like the thought of 300-500 dollars to do it. There are internaly balanced small stroke steel cranks available now without the need for mallory metal. I wuld be using a stock crank, rod and whatever piston of your choice, balanced to 28 and call it good.

+1 to woody

That's the problem I don't have any of the stock parts, I purchased just the empty block itself and would like to purchase the internals new.

Yeah, but my point is you don't need aftermarket anything.

Get stock replacement parts

Go to a salvage yard and buy a stock 5 liter out of a Mustang and use that.

Who ported the heads and what do they flow? Stage 3 port and polish has no meaning to it at all. Those Anderson valve springs won't do you any good if the cam you purchase requires different springs. Valve springs should be purchased after the cam is purchased.

JDC ENGINEering I beleive, this is the flow test data sheet:

Intake Exhaust

Valve lift CFM of air flow Valve lift CFM of air flow
.200 166 .200 110
.250 193 .250 126
.300 219 .300 140
.350 245 .350 153
.400 261 .400 164
.450 280 .450 175
.500 288 .500 183
.550 292 .550 192
.600 295 .600 201
.650 207
.700 211
.750 214

I guess I should have asked the question differently. I'm not trying to be an ass but just trying to ask questions to get a better undestanding. A stock 5 liter around here cost anywhere from $800-$1200 if im going to spend that kind of money why not buy a set of Trick flow pistons, SCAT connecting rods and crankshaft, and maybe a TFS stage 1 cam, that totals about $1500 or so. That's what I have thought about. The reason I want to build this engine is to acheive some hands on experence and learn more than I know now, and that's not a whole lot, plus it's something I want to do with my dad. I have a stock 5 liter in the car now, and want to build another one to take its place in the near future. Thanks for your replies and I hope I'm not coming across as a smartass, that's not my goal, just trying to learn.

You're not coming across as a smartass, but there's still no point to waste that money. Shit, go on eBay, craigslits, swap meet, classifieds, anything and you can find a cheap 5.0 engine. If not, just rebuild the engine. Take it all apart, put a rebuild kit in it, get it machined if you want and put it back together. Your engine block will split from top to bottom before your pistons / rods / crank breaks.

Stock 5 liters are $250 to $400 around here depending on mileage. You need to look around a bit more.

I didn't realize that the stock crank, rods and pistons could handle the abuse. Could I use TFS pistons on stock rods? Do you think it is possible to attain 375 to 425 HP with all that I have mentioned? Thanks again for clarification, it's always nice to save money!

[mikebert]

You *might* hit the bottom end (375) if you do all the little tricks (pulley, electric fan, CAI) and get a good cam, maybe a custom grind. I don't know how much extra those heads are worth over out of the box Trickflows.

[Iownastang]

Astock cast crank can handle more than the block so your ok.and as for the stock i beam rods i think they can handle 500 if im wrong someone correct me

The stock crank, rods and pistons will handle more power than the stock block will. Your horsepower goals are attainable.

[shurb125]

What type of supercharger would you reccomend for this type of set up? Please be percise, I don't know much about them, just want to start researching in the right direction. Thanks for the input

[Speedstang302]

well your going to have to stay with a low compression.which could alter that build a little..and i would say easiest way to search for s/c is look up vortech, powerdyne and paxton..they are the most common ones..
